Research on the Self excited Vibration in Wheeled Vehicle Powertrain( Part I)——Mechanism Analysis of the Self excited Vibration

摘要: 研究了轮式车辆动力传动系自激振动的机理。建立了动力传动系力学模型，对振动进行了相平面分析，得出地面附着系数随滑转率的增加而减小的特性是造成车辆传动系自激振动主要原因的结论

Abstract: In this paper, the mechanism of the self excited vibration in wheeled vehicle powertrain was studied.For this purpose, the mathematics model was established, and the analysis of the phase plane was presented.The results indicated that the main cause of the self excited vibration is that the adhesion force became smaller as the slip rate increased.
