| 摘 要： | 文章研究了传动轴扭转阻尼、半轴扭转刚度和扭转阻尼等结构参数对整车振动系统稳定性的影响，表明增加半轴和传动轴的扭转阻尼能够明显地抑制自激振动的产生；还研究了外界参数对车辆振动系统稳定性的影响规律，表明前轮和后轮的地面附着重量利用系数随滑转率的增大而减小的斜率对稳定性的影响很大，不稳定模态的正实部随这两个斜率的增加而增大；并探讨了抑制自振的一些方法和结构措施

| Abstract: | In this paper, the influences of structural factors such as torsional damping of transmission axle and half axle etc., on vehicle stability were studied, and the results showed that increasing the torsional damping of transmission axle and half axle can significantly increase vehicle stability. External factors influencing vehicle stability were also studied, and it was pointed that decreasing slope of adhesion coefficient with the increasing of wheel slip influences vehicle stability significantly. In addition, measures to control the self-excited vibration were discussed. |
