在进行车辆动力学仿真时，轮胎受力对汽车的平顺性、操纵稳定性和安全性起着重要作用。选择符合实际又便于使用的轮胎模型是建立车辆模型并进行动力学仿真的基础。(In the simulation of vehicle dynamics, the force of tire plays an important role in vehicle ride comfort, handling stability and safety. Choosing the tire model which is practical and easy to use is the foundation of establishing the vehicle model and performing the dynamic simulation.)
