According to Kant, a certain kind of knowledge is essential to the achievement of moral autonomy. In order for an action to be obligatory, it must be possible for me to know not only what I have a duty to do, but also the ground of my obligation. While Fichte too identifies the importance of this epistemic dimension of moral autonomy, some recent accounts of Fichte's ethics undermine it, either by severing the link between conscience and moral knowledge, as Michelle Kosch does, or by holding that the grounds of our obligations are not knowable by all, but only the transcendental philosopher, as Owen Ware does. I argue that we can save the connection between conscience and moral knowledge by distinguishing between conscience and conviction, but that there is an abiding tension in Fichte's ethics between the philosophical account of the ground of our duties and the discursive activity of justifying our actions to one another.

In this paper, I explore phantasy in relation to the drive and work out the hypothesis that phantasy is part of the requirement of psychic labour that the drive demands in order to subjectify the body. What distinguishes drive from instinct is the phantasy of relation: it emerges from the body, it learns from the body the procedures of functioning with internal and external reality, for the Ego before being the Ego is the bodily Ego. The phantasy of relation, as a form of investing the object with affects, sets the psyche to work in order to access the reality of the other, beyond its own pleasure principle. Going along the lines of the body drive and phantasy, I reach what I call the surreal relationship, which a person creates by denying anatomical/genital parts, subsequently repressing them. I refer to the psychic movement as an act of living immersed in the interior, denying the principle of reality in the inner life: one denies the body, parts of the drive, and the drive needs to satisfy itself with a dream or a phantasy of relation. When the principle of reality cannot be established, access to the object and access to the self are blocked. The anxiety of the body takes the form of the anxiety of the self, and relations are surreal. I use vignettes to illustrate relation phantasy and the surreal relation. [ABSTRACT FROM AUTHOR]

The motion of the processing medium inside the container performing complex spatial motion in a Turbula-type barreling machine was studied experimentally. It was established that the different rotation behaviors of the drive shaft and the driven shaft of the barreling machine create conditions that significantly „narrow" the field of application of this equipment. The law of angular velocity of the drive shaft was obtained analytically. Its implementation ensures the same intensity of motion of the processing medium in opposite directions between the opposite ends of the container and a single mode of motion throughout the entire machining process. A drive that enables implementing the law of angular velocity for the machine driving shaft was designed. [ABSTRACT FROM AUTHOR]

This paper is about music and psychoanalysis and proposes convergences between both disciplines, not to psychoanalyze the musical or musicians' activity, but to determine and describe what music can contribute to the psychoanalytic practice. To this end, it establishes relationships between some concepts proper to the aesthetic music theory and some central psychoanalytic notions to illustrate the relationships between sublimation and the death drive. The aim is to highlight that the relationship that the subject establishes with music is not only supported on the life drive or eroticism but also on the thanatic, i. e. the determinations of the drive vicissitudes traced by desire and jouissance.

Based on the patent-information analysis, the paper substantiates the relevance of researching technical and economic indicators of typical automobile power supply systems based on generator sets (GS) and starter batteries (STB). In order to carry out experimental researches of automobile GSs the authors developed a laboratory setup on the basis of high-speed electric motor powered by frequency converter with direct measurement of torque and equipped with necessary equipment and electro-measuring instruments. The methods of experimental and computational determination of the investigated indicators are presented. The results of the investigations made it possible to determine the components of power consumption for the drive of a vehicle generator set and its coefficient of performance. The consumption and cost of fuel consumed for the drive of a vehicle GS is calculated, the necessity and directions of further research on their reduction are substantiated.

Aim of the studyThe aim of this study was to assess the effects of a nociceptive stimulus on respiratory variables in anesthetized dogs.Material and methodEleven dogs received acepromazine administered intramuscularly (IM) at a dose of 0.04 mg kg−1 45 mins before induction of anesthesia. Loss of consciousness was obtained with midazolam at 0.2 mg kg−1 and propofol administered at a dose of 2 mg kg−1 intravenously (IV). Orotracheal intubation was performed and anesthesia was maintained with isoflurane in 100% oxygen. Inspired (VTi) and expired (VTe) tidal volume (VT), minute volume (VM), inspiratory and expiratory time (Ti; Te) were measured and recorded twice a second by a spirometer. The Drive (VT/Ti) and Timing [Ti/(Ti+ Te)] were calculated.After stabilizing the depth of anesthesia the variables measured by the spirometer were recorded for 5 mins [T0−5-T0]. Then (T0) interdigital clamping of the hind leg was performed until a withdrawal movement was observed. If no reaction occurred, the clamp was left in place for 60s. After removal of the clamp, respiratory variables were measured continuously for another 5 mins [T0-T0+5]. At T0+5 morphine (0.2 mg kg−1 IV) was administered. Five minutes later (T0+10), a second clamp test was performed, using the same procedure. At T0+15 the data recording was stopped.ResultThe results showed a large variation in the individual values of Drive and Timing and are presented in a descriptive manner. The observation of Drive values over time showed variations following nociceptive stimuli. Drive appears to have increased only for those dogs that did not move during the stimulus, and were therefore pinched for a full 60 s. In contrast, the study of the Timing values revealed no difference between the data before and after nociceptive stimulation. However Timing seems to increase after morphine administration.ConclusionDrive remains a parameter that needs to be studied in depth to determine its sensitivity and precocity to monitor acute nociception.

My aim with this article is to explore texts written by Georges Bataille on the basis of concepts formulated by the French psychoanalyst Jacques Lacan. I will use the concepts subject of the unconscious and drive to focus on the texts that make up La Somme athéologique. In these texts, although not expressly stating it, Bataille presents an experience of the unconscious as manifested in the drive. This experience is not mystical, but indicative of a particular type of social bond.

Prolonged wakefulness leads to an increased pressure for sleep, but how this homeostatic drive is generated and subsequently persists is unclear. Here, from a neural circuit screen in Drosophila, we identify a subset of ellipsoid body (EB) neurons whose activation generates sleep drive. Patch-clamp analysis indicates these EB neurons are highly sensitive to sleep loss, switching from spiking to burst-firing modes. Functional imaging and translational profiling experiments reveal that elevated sleep need triggers reversible increases in cytosolic Ca(2+) levels, NMDA receptor expression, and structural markers of synaptic strength, suggesting these EB neurons undergo sleep-need-dependent plasticity. Strikingly, the synaptic plasticity of these EB neurons is both necessary and sufficient for generating sleep drive, indicating that sleep pressure is encoded by plastic changes within this circuit. These studies define an integrator circuit for sleep homeostasis and provide a mechanism explaining the generation and persistence of sleep drive.

Innovative wheelchair designs require new means of controlling the drive units or the propulsion transmission systems. The article proposes a signal to control the gear ratio or the amount of additional propulsion torque coming from an electric motor. The innovative control signal in this application is the signal generated by the maximum voluntary contraction (MVC) of the muscles of the upper limbs, transformed by the central processing unit (CPU) into muscle activity (MA) when using a wheelchair. The paper includes research on eight muscles of the upper limbs that are active when propelling a wheelchair. Asymmetry in the value for MVC was found between the left and right limbs, while the belly of the long radial extensor muscle of the wrist was determined to be the muscle with the least asymmetry for the users under study. This pilot research demonstrates that the difference in mean MVCmax values between the left and the right limbs can range from 20% to 49%, depending on the muscle being tested. The finding that some muscle groups demonstrate less difference in MVC values suggests that it is possible to design systems for regulating the gear ratio or additional propelling force based on the MVC signal from the muscle of one limb, as described in the patent application from 2022, no.

Freud set forth the following principle of analytic technique: analysis must as far as possible take place in a state of refusal, of abstinence. That is what Lacan translated into « not to respond to demand ». Now, by elaborating the notion of demand and the question of its satisfaction, Lacan finally showed that the analyst must in fact satisfy the demand that deserves to be considered as fundamental.

L'article présente une étude clinique du syndrome de dépersonnalisation. Nous présentons un cas typique de cet état pour interroger les destins du sens interne dans la psychopathologie et les modes de la subjectivation de la vie dans la psychose. L'étude détaillée du cas d'Aurèlie permet de comprendre que le syndrome de dépersonnalisation confronte la patiente avec une expérience de désubjectivation où l'ex-sistence même du sujet psychologique est mise en cause. Ceci nous amène à questionner l'abord clinique de ce phénomène. Car les descriptions qui se satisfont du simple constat du désordre de certaines fonctions psychiques (telles que la sensibilité ou la perception) semblent rater l'essentiel: le fait que ce syndrome décrit un défaut majeur du rapport à la vie. Nous essayons de le démontrer. Il nous paraît nécessaire d'ouvrir une interrogation clinique, qui, en deçà de la sémiologie traditionnelle, pose la question des variations psychopathologiques non plus comme des écarts de la norme, mais comme des modes de la subjectivation de la vie. The article presents a clinical study of depersonalization syndrome. We present a typical case of this state in order to investigate the destinys of the internal sense in psychopathology, as well as the modes of subjectivation of life in psychosis. The detailed study of Aurélie's case allows us to understand that depersonalization syndrome confronts the patient with an experience of desubjectivation where the very existence of the psychological subject is put into question. This leads us to question the clinical aspect of this phenomenon. Indeed, descriptions that do not go beyond a simple observation of the disorder of certain psychic functions (such as sensitivity or perception) seem to miss the point: the fact that this syndrome describes a major defect in the subject's relationship with life. It seems necessary to develop a clinical questioning, which, beyond traditional semiology, would pose the question of psychopathological variations no longer as deviations from the norm, but as modes of the subjectivation of life.

Cet article interroge le retentissement de l'enfermement carcéral sur l'investissement subjectif du corps pulsionnel. Nous postulons l'hypothèse d'une réification de l'objet consécutive au processus d'incarcération qui retentirait directement sur l'investissement du corps propre par le sujet, comme sur ses trajectoires pulsionnelles. Nous avons travaillé à partir d'un cas de patient suivi en psychothérapie en unité de soins, en milieu carcéral. L'analyse de cas proposée illustre la manière dont l'enfermement accentue artificiellement les contours des zones laissées blanches dans la distribution libidinale du corps érogène, et la manière dont, a contrario, les zones sources favorisent des expressions pulsionnelles contraintes dans leur réalisation, pour un surinvestissement de l'intensité de la poussée alors devenu but. La manière dont nous proposons d'illustrer le dépassement de l'enfermement perceptuel dans la rencontre, ne semble pouvoir passer que par une clinique du retournement qui convoque tour à tour, et de part et d'autre, des éléments perceptifs et affectifs, loin de représentations abouties. Or, il semblerait illusoire de nier l'impact même de la représentation dans le processus associatif, ne serait-ce que par le travail narratif qui s'amorce ici, travail qui porte en lui-même les conditions du dépassement du perceptif dans le transfert. La pulsion, mise « sans dessus-dessous » par l'épreuve de l'enfermement, se délierait à l'instar d'un processus pervers favorisant les décompensations en cascades, elles-mêmes alors prétextes au cœur de la demande de soin. This article questions the impact of imprisonment on the subjective investment of the body of the drives. The author postulates the hypothesis of a reification of the object following the process of incarceration, which would have a direct impact on the subject's investment of his own body, as well as on the trajectories followed by his drives. The author exposes the case of psychotherapy with a patient in a medical care unit in a prison environment. The analysis of this case illustrates how confinement artificially accentuates the outlines of areas left blank in the libidinal distribution of the erogenous body, and how, on the contrary, the source areas constrain the realization of the expression of the drives; an overinvestment of the intensity of the constrained thrust becomes itself the goal. The possibility of overcoming perceptual confinement in a clinical encounter is only present when there is a reversal on both sides of perceptual and affective elements, at a distance from successful representations. However, it would seem illusory to deny the very impact of representation in the associative process, if only through the narrative work that begins here, work that carries in itself the conditions for going beyond the perceptual in the transference. The drive, turned "upside down" by the ordeal of confinement, tends to come undone, in a way that recalls the undoing performed perverse processes. This can lead to a series of decompensations, themselves pretexts for the demand for care. [ABSTRACT FROM AUTHOR]

The purpose of this study is to understand preadolescents as consumers and to conceptualize the process involved in their food purchase behaviour. Extant literature suggests that behaviour intention is generated as a combined effect of an individual's attitude towards consumption of the product and the subjective norms that one is exposed to. The present paper advocates that this combined effect does not necessarily lead to purchase intention amongst preadolescents and further investigates how they develop purchase intention and behaviour. A conceptual framework has been developed using the insights obtained from a thorough review of the literature and qualitative thematic analysis of 36 in‐depth interviews conducted with preadolescents (9–14 years old) in the context of their food consumption behaviour. The paper proposes an attitude–motivation–behaviour framework which postulates that a favourable socialized attitude, a strong drive and a high perceived effort collectively create high motivation to purchase, leading to purchase behaviour intention, which in turn leads to purchase behaviour amongst preadolescents. The study provides a sequential process through which preadolescents make purchase decisions; hence the proposed conceptual framework, after a quantitative validation, may serve as a guideline for marketers in targeting preadolescent segments.

The article presents the results of the experimental study of the motor drum temperature regime of a short belt conveyor. A description of the experimental stand, as well as the equipment used, is presented. The paper describes the test procedure, the initial conditions for testing at each stage. These conditions imply the nature of the change in the initial tension of the belt, the level of conveyor load, design features of the motor drum, in particular the use of a lining or the use of smooth steel shell during testing. The primary results obtained are presented in the form of decoded thermograms of the working area of the motor drum. The generalized processed results of the experimental studies are systematized in the form of graphical dependencies, which are united according to the objects of study: a motor drum, a leaving belt branch, and an entering belt branch. On the basis of the results obtained, the corresponding conclusions are made, which are the law descriptions of the thermal mode of operation with regard to the motor drum, as well as the belt branches in contact with it.

In this brief paper I argue that to understand Freud is to understand the meanings of his ideas. The choice of words to describe these ideas is usually relatively insignificant and does not in itself determine understanding. Thus, the translation of Trieb as "drive" rather than "instinct" does not change the phenomena that Freud addresses through the term Trieb, nor does it open us to the understanding of Freud's profound, complex and evolving ideas regarding these phenomena. To think that it can, in fact, limits understanding. This runs counter to a popular view that Strachey's translation of Trieb as "instinct" led the Anglo-American analytic community to see Freud as more biological and mechanistic than he actually was. Accepting the popular view would make the change of the term, which does occur in the Revised Standard Edition , seem especially significant. Evidence against this popular view may be seen in the fact that Klein and her followers, like Strachey himself, commonly use the term "instinct" and yet their understanding, which emerges from a close study of Freud in context and the phenomena to which he refers, maintains and develops the richness of Freud's thinking and does not at all offer a biological or mechanistic perspective. Important to the understanding of Freud in context are his early letters to Fliess, and thus it is very unfortunate that the unabridged version of these letters which became available in 1985 were not included in the RSE.

This paper explores the concept of drives as basic motivational neurobiological structures determining the organization of psychic life. I express my agreement with Mark Solms' radical reformulation of the general principles organizing human behaviour at the neurobiological and psychodynamic levels, his combination of Friston's computational information theory and Panksepp's affect systems. I agree with him that the affect systems described by Panksepp constitute the primary drives and that the conflicts between affect systems are the origin of unconscious intrapsychic conflict. I disagree with Solms in my proposition that, while the original unconscious conflicts indeed reflect conflicts between antagonistic affects, I believe that the integration of affect systems into internalized object relations determines a significant motivational shift: now unconscious conflicts are between complex organization of idealized and persecutory object relations at oedipal and preoedipal levels, and no longer between affect systems themselves. At the various developmental levels, the integrated fusion of affective components of these conflicts in effect evolves into libido and aggression as supraordinate motivational systems, but they no longer can be considered biological drives.

Using both formal analysis and the framework of critical whiteness studies, this paper studies the role played by lighting in the construction of Ryan Gosling’s persona, focusing on its racial dimension. More specifically, it analyzes the way the star is lit in five films of the 2010s that portray his whiteness as under threat. After a first part dedicated to Drive (2011), which plays a crucial role in shaping the star’s dual persona, the second part of the article examines the different ways in which lighting contributes to building Gosling’s whiteness as “in crisis” in the four following films : The Place Beyond the Pines (2012), Only God Forgives (2013), Blade Runner 2049 (2017) and First Man (2018).

This paper describes the relationship between technics and desire in light of Bernard Stiegler’s new critique of political economy. The starting point for the analysis is Stiegler’s critique of the reinterpretation of Freud’s legacy by Herbert Marcuse in Eros and Civilization. The context of the analysis is the ongoing mutation of consumer capitalism into computational capitalism—one in which automated calculation systems are used to control all forms of mental and affective human activity. Digital automatization, I argue, encourages a different view of what Marcuse called “the automatization of the superego.” It also requires us to rethink to what extent desire is conditioned techno-logically beyond the limits of Marcuse’s critique of Freud, capitalism and technology. The article pays special attention to Stiegler’s reinterpretation of the theory of sublimation in relation to contemporary capitalism and its technological infrastructure (from television to digital platforms). It is also an attempt to include the question concerning technology in psychoanalytic thinking.

Sigmund Freud and Georges Bataille share a similar conception about the human that tenses and tears the interpretations of the rational subject inherited from modernity. In our journey, we intend to look into the influence that psychoanalysis would have had on Bataille's heterology. To do this, we will stop at three points where Bataille's thought intersects with Freud's: surrealism, death, and the notion of subject. These will be the strings with which we will braid the encounters between these authors to arrive at the idea of a torn or split subject against any humanist aspiration. [ABSTRACT FROM AUTHOR]

Background: Due to the ubiquitous use of smartphones in daily life, they offer unique opportunities to study human behavior. This study sheds light on associations between self-reported stress, drive, and mood levels and smartphone usage behavior. Methods: A total of 157 students installed the Insights app on their personal smartphone and tracked smartphone usage behavior. Furthermore, students assessed self-reported levels of stress, drive, and mood for 8 weeks. Results: Three multilevel models were used to associate smartphone usage behavior and self-reported mood, drive, and stress levels. Results indicate a negative association of self-reported stress and number of SMS (–3.539, SE = 0.937) as well as a positive relation of stress and call duration (0.018, SE = 0.937). Mood was linked negatively with total usage time (–0.019, SE = 0.004) and call duration (–0.016, SE = 0.007). Moreover, drive was negatively associated with Facebook usage time (–0.127, SE = 0.041). Discussion: Overall smartphone usage behavior is negatively associated with measurements of well-being. Conclusion: Passive smartphone tracking could assist in the standardized assessment of behavioral data in real life in the future. Due to the risk of data misuse, ethical, legal, and clinical guidelines have to be developed. [ABSTRACT FROM AUTHOR]

The article proposes a method of reducing the power of the drive for the separation of packages of canned feed from trench storage through the use of a modified hydraulic drive system. The structure and the principle of operation of the system of hydraulic drive of mechanisms of cutting of canned forages are developed. This approach has significantly reduced the power of hydraulic motors by simultaneously controlling the cutting speed of the monolith when feeding the rod and the feed rate of the cutting device. The substantiation of modes of operation of the mechanism and ways of increase of its energy efficiency are resulted. The high competitiveness of the proposed device is proved by performing a comparative analysis of the characteristics of the manins presented on the market and agro-industrial complex equipment.

By combining linear and rotary movement in one single drive, the overall dynamics of machine axes can be enhanced, and the installation space can be reduced. Existing concepts for linear-rotary drives either have low power density or load capacity, and the installation space of the guideways are not sufficient for applications in machine tools. Thus, this paper presents a novel linear-rotary direct drive for machine tools. The electromagnetic coupling between the linear and rotary direction is analyzed, and the control performance is evaluated. The developed drive is characterized by stiffness of up to 205 N/µm, acceleration dynamics of 3,100 mm/s2 in linear and 24,100 °/s2 in rotary direction, and fine positioning in 0.2 µm and 3.6″ steps.

In both A Serious Man and Breaking Bad the concept of repetition is addressed, and reworked following a Freudian and a Lacanian take. The true repetition is what is new, and not what is obsolete, and always the same. Destiny as mere result of classical repetition, as an already there, already written, is thus confronted with the other side of repetition, that of the presence of the subject on "the scene of the world", and not merely among the spectators. Moreover, "the scene in the scene" is in both features a way of showing that the unconscious is the royal path to one's identity, in its singularity. Repetition in all its states is therefore the actual choice for the subject in order to choose its own way of dying. And, without knowing it, this is precisely what the two heroes, Larry and Walt, put forward in these pictures. [ABSTRACT FROM AUTHOR]

The paper presents a study regarding electro-hydraulic control systems for drive winches, a structural part of LARS (Launch and Recovery Systems). In the Introduction section of the paper, the authors present the domains of the research vessel. Furthermore, there is presented the importance of launch and recovery systems (LARS) and drive winches on the deck of a research vessel. The launch and recovery systems (LARS) using drive winches are installed on the stern of the research vessel. Further in the paper, the authors present the results of studying three simplified systems that use electric, hydraulic and electro-hydraulic driving solutions. Furthermore, there are presented comparative advantages of using this three types of drive winches. At the end of the paper, the authors perform an analysis of the electro-hydraulic systems for the drive winch, using a modelling and simulation software. Each schematic is presented along with its components. Moreover, the authors mention that all the schematics presented in this paper are modelled using FluidSim software from FESTO. In this case, only three mathematic relations are used in the paper: the Cauchy momentum (convective form), the incompressible Euler relations and the pressure losses in the hydraulic and electro-hydraulic drive winch.

The present article suggests that it is possible to understand the difference between life drive and death drive, in Freud, in terms of empirical and transcendental. These categories help us because they allow us to think that the organism, specifically the psychic apparatus, has two functions that can be methodologically differentiated: a transcendental function of destruction and an empirical function of construction.

ObjectiveThis study investigated the prevalence of driven exercise (DE) and its role in treatment outcome for adolescents with bulimia nervosa (BN) and anorexia nervosa (AN).MethodParticipants were 201 adolescents with an eating disorder (ED) (80 with BN and 121 with AN) presenting for outpatient treatment at two specialist clinics. All adolescents participated in one of two randomized controlled trials. Descriptive statistics were conducted to evaluate the presence and frequency of baseline DE. Exploratory hierarchical regressions were used to evaluate the effect of baseline DE on treatment outcomes.ResultsAbout 66.3% of adolescents with BN and 23.1% of adolescents with AN presented with baseline DE. The presence of baseline DE predicted significantly worse outcomes for adolescents with AN in terms of ED symptom severity (ps

This paper aims to show that Fichte’s concept of Streben or striving of the I is the necessary condition of finite or individual consciousness. The I posits itself absolutely, but in doing so it posits the not-I as well, therefore it posits itself absolutely as self-limiting I. If there was no limitation on the infinite striving of the I’s activity, then there would be no I, at least as we know it. Firstly, the paper emphasizes why this activity or striving needs to be infinite, and at the same time determined. Then, why is it necessary for theoretical self-consciousness, regarding the idea of Anstoss, divided self and absolute I. Finally, why is it also necessary for practical standpoint, considering the ideas of practical striving, tendency, longing, drive, and desire (both in individual striving towards self-coherence and social drive for intersubjectivity). It will be concluded that the I possesses a “dual nature” or divided character: it is finite, but it strives towards infinity. The tension arising from this contradiction should be the moving force of the I.

We present the first study to unravel bacterial community composition and assembly in a field-grown common garden of six contrasting pineapple cultivars in a subtropical region. Bacterial communities of plant-associated compartments (i.e., rhizosphere, root, stem, leaf and fruit) of each cultivar at the premature stage were compared. We found that alpha diversity differed between plant compartments and also genotypes, but the endophytic bacteria within compartments did not decrease sharply. The richness of bacterial communities followed a spatial differentiation with higher values in below- (root and rhizosphere) than in above-ground compartments (leaf, stem and fruit), but that in the three aboveground compartments were similar. Methylobacterium , Bradyrhizobium and Bacillus are dominant genus across different pineapple cultivars and compartments, which could be associated with the improved nutrition uptake and stress resistance. Bacterial community assembly was driven by the pineapple-associated compartment, rather than genotype. There was also clear niche differentiation of bacterial community at the below- – above-ground interface, and the similarity of endophytic bacteria between leaves, stems and fruits occurred. The community assembly in roots was primarily dominated by stochastic processes, as bacterial community in roots and rhizosphere separated each other. This study could be helpful for the effective microbiome management practices of pineapple plantation and fruit quality control. • The dominant bacterial genus attributed to the improve nutrition uptake, and stress resistance. • Bacterial community assembly was drove by the pineapple-associated compartment, rather than genotype. • There was also clear niche differentiation of bacterial community at the below- – above-ground interface. • The community assembly in roots was primarily dominated by stochastic processes.

The article presents the results of studies that showed that when monitoring the loading of the drive of the cutting body of a combine that combines vibrodiagnostics with the traditional assessment of the parameters of its functioning, its information content can be significantly increased, and the assessment of not only the state of the cutting bodies, but the actual resistance of the potash salt layer to destruction, which allows for the selection of the most rational, in terms of ensuring the highest performance, geometry and properties of the cutters, as well as a technically and economically reasonable choice of the range of variation of the speed of the combine and forecasting its performance and the cutting body associated with this technical condition. A comprehensive monitoring methodology has been developed for the electromechanical actuator of the cutting body, taking into account the influence on the loading parameters of the cutting condition of the cutting organ and the resistance of potash ore to cutting, the implementation of which makes it possible to quickly determine the causes of increased load related to either an increase in resistance of solid to cutting or breakage of the cutters for the rapid elimination of the latter.

Introduction. Precision elements of the target equipment and sensitive elements of the stabilization and orientation system of the advanced spacecraft are considered in the framework of this research. A method and software for modeling the dynamic characteristics of these elements are developed and validated. At that, the processing data results from the experimental studies on active and passive oscillators are taken into account.Materials and Methods. It is shown how the method of weightlessness provides simulation of the conditions that as much as possible conform to the real-time use of advanced space vehicles, precision structural elements, target equipment and their drives. Schemes of the corresponding experimental facilities are presented. Mathematical modeling methods, techniques of machine mechanics and dynamics are applied. Basic parameters of the proposed design dynamics, which are governing parameters in terms of the implementation of the target functions of the spacecraft, are calculated. Rational versions of layout and approximate cycle patterns of the operation of advanced space vehicles are formed to reduce microperturbations from driving gear with rotating masses.Research Results. A simulation technique for the dynamic characteristics of the drives of advanced space vehicles considering the regular oscillator operation is developed and validated. A complex of methods is presented for solving the problems of identifying dynamic parameters of a mathematical model of an advanced spacecraft based on the processing data results obtained through the experimental testing of active and passive oscillators. Two types of vibration from flywheel engines are noted. The first type is according to the commands of the position control and stabilization control system. The second type is due to residual imbalance from the solar constant meter. It is shown how these vibrations affect the dynamic characteristics of the gyro mounting seats and of the multispectral scanner for hydrometeorological support of the spacecraft. The data obtained are meant to solve the problems of assurance of the dynamic accuracy of advanced space vehicles.Discussion and Conclusions. A technique for modeling the dynamic characteristics of advanced space vehicles when operating in the precision orientation mode is proposed. The solution is based on the results of theoretical and experimental studies presented in the paper, and it considers the operation of standard oscillators. The implementation of this method is brought to software and algorithmic support for assessing the dynamic characteristics of standard oscillators of an advanced space vehicle. Recommendations to reduce the effect of active oscillators are established. Initial data are selected to determine the dynamics of advanced space vehicles from the point of view of fulfilling their target functions. The layout and approximate cycle patterns of the operation of advanced space vehicles to identify the driving gear with rotating masses as sources of micro-perturbations are proposed.
