| 摘 要： | 基于一种轮胎非线性侧偏特性模型,利用近似解析方法研究了汽车的操纵动力学问题,给出了表征汽车稳态响应的横摆角速度增益、转向半径之比、前后轮侧偏角之差的近似解析解.结果表明,当前轮输入角较大时,稳态横摆角速度增益会迅速增加;而当车辆高速行驶时,即使前轮输入角很小,转向半径之比也会很大.与线性轮胎侧偏特性模型相比,考虑轮胎侧偏特性的非线性时,转向不足的区域明显减小. |

| Abstract: | A nonlinear perturbation model based on the cornering behavior of tires is used to discuss the dynamic handling of vehicles by the approximate analytical method.The steady-state response of vehicles,the yaw angular velocity gain,the turning radius ratio and the difference between the lateral angles of the front and rear wheels have been focused on.It is found that the yaw angular velocity gain increases rapidly if the angular of the front wheel is large.When velocity of vehicles is high,the turning radius r... |
