Analysis of oscillations of a mechanical system with inertial exciters at an alternating position of it’s mass center

Abstract

Numerical simulation results of dynamics of a mechanical system with self-synchronizing unbalance exciters with displaced center of mass relative to the initial centered state are described in application to analysis of dynamics of vibrating machines with variable position of operation load. Features of self-synchronization of exciters are revealed depending on position of the center of mass. Influence of position of the center of mass on resonance frequencies and modes is presented.
