摘要:

以205/55R16型子午线轮胎为研究对象,对配有ABS系统的汽车在湿滑路面上的制动距离进行了仿真研究。基于制动过程离散分析方法,使用有限元商业软件ABAQUS仿真研究了不同复杂胎面花纹及不同胎面材料轮胎在1.5mm深积水路面、各离散速度下的制动情况。然后根据各有限元仿真结果,使用相关分析方法,获得了轮胎的制动距离。仿真结果均与对应的试验结果趋势一致,证明了轮胎湿滑路面制动性能仿真评价方法的有效性。

Abstract:

For 205/55R16 radial tire, a numerical investigation of wet-road breaking distance for the vehicles equipped with ABS system was presented. Based on a discrete analysis method, the braking process of tires with different complex pattern and different tread materials on the wet-road with 1.5 mm depth in a series of discrete speeds were studied by using the commercial FEM codes-ABAQUS. According to the results of the simulation, the braking distance was obtained via correlated analysis method. The consistence of the simulation with the corresponding test validates the effectiveness of the method. 

Key words: finite element method(FEM), ABAQUS, wet-road, radial tire, braking distance
