Resumen

The generalized dynamic model of the rotor system, presented in this paper, is the first model that takes into account the interconnected oscillations of the ?rotor?weakly conductive fluid?foundation? system under the action of parameters such as fluid and rotor motion, linear eccentricity, friction forces, foundation vibration and nonlinear characteristics of rolling bearings, as well as the action of a magnetic field on the fluid. Consistent equations of motion for the ?rotor?weakly conductive fluid?foundation? system were derived and solved analytically. Forced and natural oscillations of the system were analyzed, and the distinctive features of the rotor system dynamics were revealed. The values of frequencies and amplitudes, which are one of the main factors determining the dynamic behavior of the system, were obtained and studied.
