| 摘 要： | 基于MATLAB/SIMULINK,以3自由度汽车非线性动力学模型为基础,建立仿真模型对汽车行驶姿态进行仿真研究,并且模拟了汽车在极限行驶工况下的行驶姿态,较低的行驶速度,适当增加侧倾转向系数可以提高汽车的操纵稳定性。前正/后负车轮外倾角可以保证汽车在高速转向/制动时保持一定的恢复横摆力矩,提高行驶安全性。改变侧倾阻尼系数对高速转向的操纵性影响不大而对行驶的平顺性有较大影响。

| Abstract: | The dynamical model of a vehicle system with 3 degree is constructed in this paper.The simulation model is also established and the method to simulate the dynamical characteristics of the vehicle system especially in extreme motion is introduced in detail.The relatively low vehicle speed and propriety adding the roll steering coefficient can improve the vehicle handing and stability.The suitable camber angle can support the correspond yaw moment and improve driving safety.Changing the roll damping coefficient has notable effect on the comfortable riding. |

| Keywords: | MATLAB/SIMULINK yaw rate side slip angle vehicle dynamic roll angle |
