| 摘 要： | 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。

| Abstract: | The principle of tire hydroplaning was presented in the paper.Through the simulation of the tire running process on the dry/wet pavement,the variation of the contact force between the tire and the ground were compared in these two cases with the increased velocity.Meanwhile application of the momentum theorem,the hydroplaning velocity formula was established.And the relationship between the critical velocity and contact force was obtained. |
