摘　　要：轮胎水滑作为车辆在雨天行驶工况下的一种常见现象,对道路交通安全有严重的危害。本文分析了水滑现象的产生原理并对轮胎水滑测试方法做了简述。分别对比了车辆牵引力控制系统、车辆载荷、花纹形式及花纹沟深度、轮胎胎压对轮胎水滑程度的影响,研究表明装备牵引力控制系统、更大载荷、装备纵向花纹沟布置且花纹沟体积较大的轮胎、胎压较大的车辆的拥有更高的水滑临界车速。As a common phenomenon, tire hydroplaning often occurs when vehicles are driving in rainy day, which has serious harm to road traffic safety. This article analyzes the generation principle of hydroplaning phenomenon and studies the method of passenger car hydroplaning test. This paper compares the effects of vehicle traction control system, vehicle load, pattern form, groove depth and tire pressure on tire hydroplaning, the result shows that vehicles equipped with traction control system, greater load, longitudinal groove and larger groove volume, and higher tire pressure have a higher critical speed of tire hydroplaning.
