摘要
建立了二自由度4WS汽车系统的动力学模型,给出了相应的动力方程。同时从理论上分析了这一系统的稳态和瞬态响应问题。在考虑横向轮胎力非线性效应的影响下进行了相应的理论分析与数值计算,与传统的前轮转向系统对比分析,得到采用同相位转向的4WS汽车明显有利于提高车体的行驶稳定性的有益结论。
A 4WS vehicle dynamic model with two degree-of-freedom is presented, the corresponding dynamic equations of this model are established,and the steady state and transient responses of this system are also analyzed,the nonlinear tyre forces are taken into account. The numerical computation is carried out. Through the comparison with the typical steering of front wheels, some beneficial conclusions are obtained.
