Abstract
The goal of this paper is to concentrate on dynamics and vibration attenuation of the electromechanical system flexibly coupled with a baseplate and damped by a double impact element. The model is constructed with four degrees of freedom in the mechanical oscillating part, three translational and one rotational. The system movement is reported by five mutually coupled second-order ordinary differential equations. There are the most important nonlinearities: stiffness of the support spring elements and internal impacts. As the main results it is shown that the double impact damping device massively attenuates vibrations of the rotor frame for a suitable choice of mass of the impact elements in dependence of the excitation amplitude of the baseplate.
