On qualitative methods in the investigation of the nonlinear oscillations mathematical models in some electromechanical systems

The qualitative results on the well-posedness of the problems about the nonlinear oscillations in the mechanical subsystems as components of some general electromechanical systems are obtained. Basing on these results and analog computation there is verified the sufficient adequacy of the obtained mathematical models of the nonlinear oscillations to their real prototypes. It is shown that the nonlinear environment conducts the quicker oscillation attenuation and causes the anharmonic processes in the system.
