| 摘 要： | 由于轮轨黏着曲线的负斜率,动车传动系统扭转振动会演化成自激振动,使振幅增大,对传动不利。文章建立简化的动车传动系统扭转振动数学模型,通过Simulink计算仿真,利用相平面分析方法,再现了轮对平均滑转率大于临界滑转率时,扭转振动稳定的极限环,证实了传动系统产生稳定的自激扭转振动。

| Abstract: | The torsional vibration of drive system on locomotive turns into unstable self-excited vibration because of negative slope of adhesion curve.Augment of the vibration amplitude is bad for transmission.A simplified mathematical model about torsional oscillation of drive system on locomotive is put forward.Using the phase plane method and Simulink,the phase trajectory of the torsional vibration is drawn and verified to be a stable limit cycle which signifies self-excited vibration. |

| Keywords: | drive system of locomotive self-excited vibration torsional vibration phase plane |
