车辆行驶路面多种多样,如干路面、湿路面、冰路面、雪路面和土路面等。轮胎是车辆与行驶路面之间的唯一接触点,而轮胎牵引性能随着不同路面条件发生相应的变化。轮胎牵引性能是决定车辆安全性能的关键因素,可通过数值模拟的方式研究不同路面条件下轮胎牵引力的变化情况。例如隐 Vehicles driving a variety of pavement, such as dry pavement, wet pavement, ice pavement, snow pavement and dirt pavement. The tire is the only point of contact between the vehicle and the road surface, and the traction performance of the tire varies with different road conditions. Tire traction performance is the key factor that determines the safety performance of the vehicle. Through the numerical simulation, the change of tire traction under different road conditions can be studied. For example, hidden
