1. Structural Analysis and Construction of the Operating Area of an Isomorphous Translational–Directional Mechanism with a Parallel Structure.

Author

Edakina, T. V., Lastochkin, A. B., Gavrilina, L. V., Kasilov, V. P., and Ramzhaev, V. S.

Abstract

An isomorphic translational–directional mechanism with a parallel structure is considered. By isomorphism, we understand a kinematic decoupling and constancy of translational relations between the movements of the drives and the output link. To ensure the rotation of the operating body around the single axis, the mechanism is equipped with an additional kinematic chain, including two Hooke's hinges. The structural analysis, the construction of the operating area, and the design of the operating model are considered. [ABSTRACT FROM AUTHOR]

2. Numerical Method for Determining the Operating Area of a Robot with Relative Manipulation Mechanisms.

Author

Gaponenko, E. V., Rybak, L. A., and Malyshev, D. I.

Abstract

In this paper, we consider the application of optimization algorithms to solve the problem of determining the operating area of a robot with mechanisms of relative manipulation based on a plane 3-RPR mechanism and a tripod mechanism. A method for approximating the set of solutions to a system of nonlinear inequalities describing constraints on the geometric parameters of the robot is considered. Algorithms for constructing the operating areas of individual mechanisms were synthesized. The orientation effect of the output link on the size and shape of the operating area of each mechanism is analyzed. The operating area of the robot is obtained taking into account the constraints on the geometric parameters of the workpiece being in a moving coordinate system located in the center of the flat 3-RPR mechanism, as well as taking into account design constraints, intersections of links, and special positions.

Abstract

The research objective is to study the development of the noise spectra patterns in the operating area of copy mill operators. The experimental studies have shown that among harmful factors specific to these machines, there is an octave sound pressure level increase up to 15 dB in the idle mode and up to 15 dB under woodworking. These data suggest that the main noise source creating excess over the maximum permissible values is a spindle unit, and in particular, the spindle case. The vibration measurements on the machine carrier system have confirmed the results of the noise monitoring. The main source of the increased vibration levels for these machine tools is spindle rolling-contact bearings.

Abstract

In this paper, a working-process simulation model was established, and the characteristics regarding the diesel engine maximum output power were analyzed under different limiting parameters. The design margin of the marine diesel engine is obtained through numerical and experimental study. Then, the simulation model and single cylinder diesel engine test were used to investigate the theoretical determination method of limiting characteristic lines and design margin area. It can be found that using least-square method to fit the calculation results can achieve quantitative analysis of limiting characteristics, and then the design margin area can be confirmed. The analysis results show that the maximum output power of the diesel engine is limited by in-cylinder pressure, turbine speed and exhaust temperature. The limiting parameters of maximum output power are different at different speeds, and the trend with speed of maximum output power are also different under different limiting parameters. Furthermore, the analysis of the operating area shows that the margin of the marine diesel engine at rated speed is about 27%, and there is a large design margin when operating at high speed.

9. Enabling sustainable transportation: The model-based determination of business/operating areas of free-floating carsharing systems.

Author

Seign, René, Schüßler, Maximilian, and Bogenberger, Klaus

Abstract

Free-floating carsharing systems with (and without) electric vehicles are emerging and there is limited knowledge where such concepts will succeed, regardless of their environmental benefits. Within this knowledge gap, the definition of the business/operating area is a key aspect. Inside this area a carsharing vehicle can be picked-up and dropped-off everywhere at any time. This research develops a model that helps to determine business areas a-priori by predicting inner-city booking hot-spots. The approach is based on modeling success factors as independent variables, namely population density, housing rent, city center distance, and hotel/restaurant density. With the help of these variables predictions for geographic zones in cities are made that prove to be helpful for designing operating areas for free-floating carsharing systems – a key challenge for providers' success when approaching new cities.

Abstract

The article considers some issues of matching the operating area of the Doppler shortrange location system (SRLS) with the destructing area of a fragmentation warhead in a wide range of applicability with no information about the angular position of the target.When action is against the low altitude aerial targets at the sea surface background Doppler SRLS are often used to provide frequency selection of a target owing to differences in the spectral characteristics of the required signal and interferences. However, Doppler systems have an inherent disadvantage i.e. the inability to estimate the angular position of the target wit respect to the SRLS.Consequently, an arising problem to ensure the effectiveness of the combat unit, which includes the guidance system, Doppler SRLS, and fragmentation warhead is of significant practical use, when acting against the low altitude aerial targets in a wide range of encounter environment with a lack of information about the angular position of the target. The article considers a practical method for ensuring the effectiveness of the combat unit by selecting the width of the destructing elements separation angle and its orientation in space.An approximate method of geometric matching the scopes of warhead and SRLS based on computer aided numerical calculation is used. With the geometric approach to the efficiency estimation in any desired angular position of the target, Doppler SRLS should form a command to burst the warhead ensuring the straddling of the target by the field of destructing elements in an arbitrary predetermined point of conditions.Algorithms of the warhead and SRLS functioning are developed and utilized as applied programs. A Doppler SRLS model is proposed. The SRLS is integrated with semi-active Doppler homing head in case there is small-sized radar target. The article presents a mathematical description of the fragmentation warhead for relatively small misses, ignoring the air resistance. It considers a procedure for forming the predetermined detonation angle of the Doppler SRLS and discusses the features of its implementation in case of large angles of the velocity triangle with a wide-angle warhead.As examples to confirm an efficiency of the developed algorithms and programs, results are given which reflect numerical calculations for some typical SRLS functioning in a wide range of the changing angles of the velocity triangle and relative velocities.The developed approach can be used for the justification of requirements for the operating accuracy of Doppler SRLS at different design stages, including the initial phase just when forming a conceptual structure only of combat unit.
