Abstract
Based on the theoretical basis of rotor dynamics and nonlinear dynamics,it introduces the rotor system with coupling of the crack-rubbing and loose faults,establishes the model of bearing faults rotor system dynamics,uses Runge-kutta method to simulate gas film force,crack and local rubbing loose with coupling faults of the rotor system.It shows that the phenomenon of the rotor system is periodic,cycle and chaotic motions.The result provides the theory basis of rotor system for the safety work.
