The studies talk about the features of moldboard and milling tillage. An analysis of current trends in the field of soil cultivation allows us to conclude that currently special attention is paid to reducing the energy intensity of the processing process. Forestry machines with bar working bodies have undoubted advantages over moldboard and milling machines, since during their operation they require much less power. Two transmission schemes were considered - chain and branched. When considering chain circuits with several variants of flywheels and passive working bodies, significant amplitudes of oscillations in transmissions appeared in the region of natural frequencies, and resonance phenomena when the frequencies of forced oscillations coincided with natural ones. Calculations have shown that an increase in the moment of inertia of the tractor engine flywheel by 3.14 times does not have a significant effect on the change in the natural frequencies of oscillations in the propulsion drive transmission, but causes them to decrease by 1.4 times. It follows that when the moments of inertia of rotating masses change, it is necessary to analyze the vibrations that occur in branched transmissions with active bar working bodies with significant moments of inertia.

The paper examines the problems of forming technical requirements for the automation of central heating points of fuel and energy complex enterprises. The main technological schemes that are subject to automation are considered, the basic requirements for the installation of technical automation equipment are shown, the basic requirements are identified based on modern concepts for constructing automated control systems, and the main adjustable and controlled parameters of the central heating station for the main application in State Unitary Enterprise “Fuel and Energy Complex” are clarified.

The article analyzes the factors affecting the soil, which directly affect the yield. Modern domestic agricultural machinery mainly has technical and technological solutions that make it possible to significantly advance in the direction of ecological balance of the impact of crop production on soils. These include non-fallow, combined techniques of basic and pre-sowing tillage, as well as the use of a new complex of heavy agrophilic running systems of heavy mobile power facilities.

The past period of economic and agrarian reforms has shown that actively applied measures to radically change production relations have not yet yielded positive results, since the mechanism for creating the appropriate productive forces, and especially from the active technical part, has not been developed. The need to improve management methods in the field of equipment operation is dictated by the deepening contradictions of an economic, technical and environmental nature. They can only be resolved through a systematic approach. The article provides an analysis of the development of interrelated complex and differentiated standards for the need for material, labor and other resources for various levels and modes of planning.

The issues of choosing structural control schemes for finishing lines for products made of natural wood are considered. A literature review is given. In the block diagrams of these systems, single-level, two-level and three-level systems can be used, depending on the complexity of the control object and control tasks. The criteria by which it is necessary to choose structural control schemes and TCA tools are shown. Block diagrams of direct (direct) digital control of the process can be considered optimal. For these purposes, an algorithm for the direct control process is given.

This article presents an analytical survey of internationally accepted samples for the assessment of online courses. By reviewing existing practices from around the world, the article identifies common approaches and methodologies used to evaluate the quality of electronic courses. This approach utilizes a combination of simple numeric values and fuzzy linguistic variables, which are then aggregated using fuzzy logic. This combination of numeric values and linguistic variables allows for a more comprehensive assessment of electronic courses. It takes into account both quantifiable factors, such as completion rates or assessment scores, as well as subjective factors, such as user satisfaction or engagement levels by utilizing fuzzy logic, the proposed approach is able to handle the inherent uncertainty and subjectivity in some of these indicators. The proposed approach aims to provide a more robust and accurate evaluation of the quality of electronic courses. It builds upon internationally accepted samples and incorporates a combination of objective and subjective indicators, using fuzzy logic to handle the varying degrees of uncertainty. This approach can contribute to the development of a standardized and comprehensive system for assessing the quality of electronic courses.

Representation of information about the surface of movement in the form of discrete maps of patency is used in problems related to the management of autonomous vehicles. The technology was developed for use on rovers. The areas of autonomous transport, transport and technological machines operating in an artificial and natural environment, mobile robots seem to be promising. The principle of building maps of patency and methods for choosing the trajectory of movement have a great potential for expanding the volume of information entered into the cells of the map, variability of the approach to the criteria for optimality of the trajectory, etc. The basics of the technology for preparing information about the area, the principles of using this information in solving the transport problem are presented, simple examples are given.

The article proposes a method for calculating the static position of the machine body. The mathematical model of the running gear is given. The dependence of the position of the center of mass in height relative to the ground on the pre-tension forces, as well as the angular deviation of the longitudinal axis of the hull from the horizontal position, is shown. A control calculation was performed, the results of which are presented in the form of graphical dependencies. The numerical experiment was carried out on the example of a tracked vehicle of a light category with a rear drive wheel.

The paper presents the results of a study aimed at ensuring the maintainability of crankshafts, as well as the importance of the need to restore worn crankshaft journals, an analysis of existing methods and an innovative method developed by the authors. The essence of which lies in the fact that each neck of the shaft is subjected to copper plating by contacting at the moment of rotation with a swab dipped in a solution of copper sulphate in water and in an electrolyte. Then, on each neck, plates obtained by rolling from a mixture of brass powder and powders of hard alloy materials (tungsten carbides, titanium, etc.) are mounted by wrapping around the neck, with layers of pasty flux from borax, brass powder, and soldering fat deposited on their surface. Further, with the help of a detachable inductor fixed in the tool holder of the machine, each neck is subjected to heating in turn. Moreover, when the inductor is turned on, a low frequency is first used to increase the depth of heating, and then the frequency increases.
