Abstract
The problems of stabilization resonant modes of a vibrating machine oscillation, excited by an unbalanced rotor of an asynchronous AC electric motor, are considered in the paper. A design diagram and a mathematical model of the machine taking into account the interaction of the oscillating system with a vibration exciter, as well as a slow change in the mass of the process load and its position on the working body, are presented. The influence of the process load mass and its position on the working body on the frequency characteristics of the system, as well as on the oscillation modes and on the forms of self-synchronization of unbalance vibration exciters is established. A numerical algorithm for automatic adjustment to the resonant mode under conditions of changing technological load is proposed. The schematic diagram and calculation of the parameters of the debalance with automatic change of its static moment depending on its rotational speed are presented.
