Abstract

Vibration and noise caused by the eccentric rotor system in operation seriously affect the safety of equipment, so it is necessary to study the dynamic characteristics of the eccentric rotor system. In this paper, the dynamic theoretical model of the eccentric rotor is established based on the Timoshenko beam-shaft theory, and the dynamic characteristics of the eccentric rotor system under different rotate speeds are analyzed by the finite element method. Results show that the vibration of the eccentric rotor system is significantly correlated with the mode and dominant frequency of the rotor system. When the speed of the accelerated eccentric rotor system is close to the critical speed, the resonance between rotation and precession will occur, and the vibration amplitude of the rotor system will increase significantly.
