| 摘 要： | 为了分析轮胎侧偏刚度对汽车前轮角阶跃输入下车身横摆角速度瞬态响应的影响,建立汽车运动的二自由度平面模型,解析分析了轮胎侧偏刚度对瞬态响应的影响。利用在ADAMD/Car中建立的整车模型进行仿真试验验证,解析分析结果与虚拟试验基本相符,得出适度增大后轮侧偏刚度,有利于提高汽车转向时的操纵稳定性的结论。

| Abstract: | In order to study the effect of tire cornering stiffness on vehicle body's yaw angular velocity transient response when there is a front wheel step steer input,a two DOF planar model of vehicle's motion is estab- lished and the transient response expression is given.By using the virtual model established in ADAMS/Car to check the validity of the above analysis,the accordance of the analysis and the virtual test is found and the conclusion that moderate rear tire cornering stiffness increase is good for improving the vehicle's control stabili- ty while turning. |
