Abstract

The main aim of this paper is to focus on dynamics of the electromechanical system flexibly coupled with a baseplate and damped by an impact element. The model is constructed with three degrees of freedom in the mechanical oscillating part, two translational and one rotational. The system movement is described by three mutually coupled second-order ordinary differential equations. Here, the most important nonlinearities are: stiffness of the support spring elements and internal impacts. As it is shown in the main results, the impact damping device attenuates vibrations of the rotor frame in a wide range of the excitation frequency and the system is showing periodic and chaotic behavior.
