Research on Simulation Technology of Hydroplaning of Passenger Car Tire

以轿车轮胎为研究对象,采用Abaqus软件CEL技术,研究带花纹轮胎和光面轮胎稳态自由滚动和瞬态滚动的建模技术,实现轮胎水滑现象仿真。分别对不同行驶速度、不同积水深度下带花纹轮胎的水滑现象进行仿真,通过对比不同情况下轮胎与路面的垂直接触力以及带花纹轮胎与光滑轮胎的水滑现象表明,该仿真技术可靠,适用于带花纹轮胎和光面轮胎水滑现象的研究。

Taking a passenger car tire as the research object, the models of tire with tread pattern and smooth tire under steady-state free rolling and transient rolling were studied by using Abaqus software and CEL technology,and the simulation of tire hydroplaning was achieved. The hydroplaning of tires with tread pattern was simulated under different driving speed and different water depth. The vertical contact forces between tires and pavement under different rolling status, and the hydroplaning results of tire with tread pattern and smooth tire were studied and compared. The results indicated that the simulation technology was reliable and suitable for studying the hydroplaning of tires with and without tread pattern.
