Abstract: The object of research is geometric models of the process of incremental forming of parts from sheet material. The subject of research is a graphical model for finding the optimal values of the parameters of the forming process based on multidimensional descriptive geometry. The author of the article discusses the main optimizing factors and process parameters. Particular attention was paid to the problems of constructing geometric models for determining the optimizing factors for incremental forming. The research method is a way of constructing a graphical optimization model of the process using the projection drawing of Radishchev for multidimensional space. Mathematical modeling was also applied to check the correctness of the obtained optimal parameters.

Abstract: The slicing technology of hard-brittle materials by endless diamond wire saw has the advantages of higher moving speed of wire saw, better slicing quality, and thin kerf. According to the strength of wire saw, the cutting force and the random vibration of wire saw, the slicing parameters are optimized. As single crystal silicon is sliced, the constant feed force is less than 10N, the maximum pretension is 30N, and the highest moving speed of wire saw is 24m/s. But because the restrict of machine precision, the highest slicing speed is 16m/s.

Abstract: The study concentrated on a radial telescopic-type tire building drum, analyzed the frameworks and working principle. Make motion analysis and dynamic analysis for the frameworks, research the relations of speed, acceleration between them, and analysis the mechanical efficiency of them. Determine the main parameters that affect the motion and force transmission characteristics of the mechanism. On this basis, we optimize the parameters and make of general guidelines for preferences and design. Using the software SolidWorks to make three-dimensional entity modeling, assembling and motion simulation. By the check analysis of the software, improve and optimize the design.

Abstract: The authors provide inverse method algorithm for invention mechatronic systems in vibrotechnics. The main difference of this method compared to a simple analysis method is that initial subsystem is solved before a synthesis of real system optimal control task for abstract. After the calculations optimal control law is found, which allows synthesizing series of structural schemes for real systems to close initial subsystem. It is also shown that near the optimal control excitation new structural schemes may be found within three kinds of strongly non-linear (impact) systems: systems with excitation as a time function; systems with excitation as a function of phase coordinates only; systems with mixed both excitations.
