| 摘 要： | 以BJ212汽车为研究对象，建立了车辆系统动力学模型，并进行了仿真计算。绘制出模拟逐步加载条件下半轴扭矩及桥壳垂直振动时间历程曲线。当车辆的平均滑转率大于滑转率门槛值时，系统将产生稳定的自激振动。通过试验验证了所建立车辆系统动力学模型及理论分析的正确性。

| Abstract: | A self excited torsional vibration on power train at high slip has influences on vehicle performances, shortens the life span of vehicle transmission parts and decreases their efficiencies. A 21 degrees of freedom model of vehicle vibration was established to simulate a vehicle nonlinear controlling system. The experimental results showed that when the average slip was less than the threshold of the slip, no self excited vibration would happen in the power train; when the average slip was greater than the threshold, the self excited vibration would be 10 Hz in the power train; and the theoretical vibration amplitude and the regular pattern coincided with the experimental results. |
