| 摘 要： | 在简化力学模型的基础上,基于非线性轮胎力模型,利用拉格朗日能量法建立了汽车四轮转向系统动力学模型,包括俯仰、侧倾、侧向、横摆及垂直五个自由度。探索了利用能量法建立动力学模型的思路,该模型能够反映汽车实际结构参数对汽车的影响,对于发出合理的四轮转向控制系统有重要的指导意义。

| Abstract: | Based on the predigestion of dynamics model,using non-linea tire model and the energy method of La- grange equation,a four-wheel-steering system dynamics model of five degree of freedom was built.The model can re- flect the effects of main parameter in practical structures on the vehicle.It has great value for researching control u- nit of the four-wheel-steering system. |
