| 摘要: |
| 针对一类非线性转子系统，建立了碰摩模型。在此基础上，通过模型的动力学仿真分析，研究了非线性碰摩转子系统的同频、倍频、分频、拟周期和混沌振动及其出现特点。其中揭示的振动特征对转子系统的状态识别与诊断具有一定的意义。 |

| Abstract: |
| A rub-impact model of nonlinear rotor system is built.Based on the model and using numerical calculation,the responses of nonlinear rub-impact rotor systems,such as period-one motions,sub-harmonic and super-harmonic vibrations,quasi-periodic motions and chaotic motions,are investigated.Nonlinear vibration characteristics of a rub-impact rotor revealed in this paper are of great significance to the condition monitoring and diagnostics of the rotor system. |
| Keywords: nonlinear rotors rub-impact phenomena feature extraction fault diagnosis |
