Object of research is dynamic processes in mechanical system of belt conveyor of clamp forming with built hydraulic and electric drives. The aim is to improve the technical level of clamp forming by ensuring their reliability, increase productivity, reduce energy and material consumption by improving methods for the analysis of dynamic processes in mechanical systems of conveyors. Methods: theoretical studies were conducted using numerical and numerical-analytic methods of vibration theory (finite element method, the method of generalized displacement and method of initial parameters). The study of non-stationary processes based on the joint integration of linear differential equations of hydrodynamic phenomena or electromagnetic condition of the engine and a set of ordinary differential equations and partial differential equations that describe the motion of a mechanical system. The result showed: - design features arrows handling machines, analyzes the rational layout of they drive belts, discovered factors influencing the possible occurrence of resonant modes, set the perspective of using hydraulic drive. It is shown that by means hidroautomatic can significantly reduce the dynamic forces in a conveyor belt during starting modes, and when running conveyor with variable loads to ensure continuity of workflow by enabling automatic backup engine control device. Done reasonable and rational choice of the type of drive circuit device and its proposed design for the belt conveyor of clamp forming. The generalized mathematical model and generated algorithm of natural frequencies and forms of free oscillations of mechanical conveyor system with an arbitrary number of sites transporting body. A mathematical model of transients hydraulic drives aggregate conveyor belt and unsteady operating modes of long belt conveyor with hydraulic drive. The method of calculation of dynamic phenomena in mechanical conveyor belt system for analysis of transient continuous transport of cars considering moving boundaries of long elastic links and indissoluble interaction of dynamic phenomena hydraulic unit and mechanical parts of the drive. Application: Conveying equipment, equipped with boom structures arranged them pipelines, mining, mining, food industry.
