摘要：
A dynamic model of the coupling rotor-bearing system with slowly varying mass was set up. The complex characteristics of the rotor-bearing system were numerically studied. There exists complex nonlinear motion of periodic, quasi-periodic and chaotic in the response of the system. In the region of sub-critical rotating speed, the main response of rotor system with slowly varying mass are quasi-periodic motion and chaotic motion; but it with no slowly varying mass is chaotic motion. In the region of super-critical rotating speed, the main response of rotor system with slowly varying mass is chaotic motion; but it with no slowly varying mass is chaotic motion and periodic-3. It may provide basis for diagnoses of the rotor-bearing system with slowly varying mass.
