Purpose: to improve the technical level of clamp-forming machine by increasing performance, reduce energy and material consumption by improving methods for the analysis of dynamic processes in mechanical conveyor systems through the application of rational continual-discrete computer models and taking into account the inseparable relationship hydrodynamic or electromagnetic processes in engines, dynamic phenomena in mechanical parts of drives in conveyor belts and in hold designs constructions. Methods: theoretical studies were conducted using numerical and numerical-analytical methods oscillation theory (finite element method, generalized displacement method, the method of initial parameters). The result obtained, rational layout installed on the boom of clamp-forming machine with developed hydraulic conveyor. With the help of hydro automatic can significantly reduce the dynamic forces in a conveyor belt during starting modes and for its work with variable load. The generalized mathematical model and calculation algorithm formed natural frequencies and forms of free oscillations of mechanical systems and conveyor boom designs. The factors influencing the possible occurrence of resonant modes. Mathematical models of hydraulic drives transients unit conveyor belt, unsteady operating modes of long belt conveyor with hydraulic drive. The method of calculation of dynamic processes in mechanical conveyor belt system, which allows to perform dynamic analysis considering the indissoluble interaction of dynamic phenomena and hydro electric wave and lengthy processes of elastic links. Finite-element discretization of nonlinear equations with partial derivatives reduces to solving the integration of systems of ordinary differential equations using standard procedures, helps construction of simple and efficient computational algorithm. Established the need to consider during the dynamic calculation of material degradation long exploited structures. Confirmed effectiveness using inertial Hydro drive for intensification of technological processes when downloading the main production line conveyor crushing rubble. Scope: materials handling equipment, is equipped with a boom structures arranged on them pipelines, mining, mining, food and more.
