| 摘 要： | 汽车爆胎后爆胎车轮半径变小，引起车身姿态的变化，从而导致载荷发生转移．载荷的转移又会引起车轮上侧偏力及回正力矩的变化．通过分析这些变化，建立了关于汽车及其转向系统的爆胎新模型．利用Simulink搭建仿真模型，得出汽车在爆胎后的侧向速度、横摆角速度的变化特征，为以后控制研究工作奠定了理论基础．

| Abstract: | The radius of a flat tire decreases after puncturing,which causes the body posture altered. Therefore, the load transfer brings the change of the lateral force and aligning torque acted on the wheels. The new flatting model of vehicle including a steering system is established through analysis of all the changes.Then the characteristic of lateral acceleration and yaw rate is developed by building the simulation model,which establishes a theoretical foundation for further study on the control works. |
