介绍了轮胎水滑现象的主要过程,通过仿真轮胎在干、湿路面上的行驶过程,比较了这2种情况下随汽车行驶速度的增大轮胎与地面接触力的变化,并应用动量定理建立动力水滑临界速度公式,得出了轮胎水滑临界速度与充气压力及载荷之1/2次方成正比的关系。
The main process of water sliding phenomenon is introduced. By simulating the running process of tire on dry and wet road surface, the contact force between tire and ground is increased with the increase of vehicle traveling speed in these two cases. The momentum law is used to establish The formula of the critical speed of dynamic water sliding is deduced that the critical speed of the water slide of the tire is proportional to the 1/2 pressure of the inflation pressure and the load.
