Abstract. The task of modernization of high-frequency harmonically resonance vibratory table with an electromagnetic drive is considered. An idea of modernization consists in the increase of technological possibilities by realization of two-frequency resonance office by a change of stiffness and inertia parameters of the two-mass machine. The initial of two-mass system is translated in three-mass, which has two eigenfrequencies of vibrations, which are determined by resiliently and inertial parameters of the system. The formula to calculation of stiffness parameter of the additional module is got, based on a task of synthesis of multipleness of eigenfrequencies of the three-mass oscillating system and provide of the two-frequency resonance mode. Inertia of oscillating mass on descriptions of acceleration of working mass (maximal value and betweenness by his harmonics value) the influence is studied. Models for description of vibrations in the probed oscillation systems, which take into account the chart of feed of electromagnetic vibroexciters, structure of the system, its parameters and influence of load on the mass-damping descriptions of working mass are offered.

Keywords: vibratory table, electromagnetic drive, resonance, oscillation system, eigenfrequencies.
