| 摘 要： | 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。基于有限元商业软件ABAQUS,采用制动过程离散分析方法,考虑ABS功能和路面积水与轮胎间的流固耦合作用,仿真研究了某纵向沟槽花纹子午线轮胎在10mm积水路面各离散速度下的制动情况。根据有限元仿真结果,使用相关分析方法,获得了该轮胎的制动时间和制动距离。对干、湿路面轮胎制动性能仿真结果进行了比较,验证了轮胎湿滑路面制动性能仿真评价方法的有效性。

| Abstract: | A numerical investigation of wet-road breaking distance for the vehicles equipped with ABS system was presented. Considering the operation of ABS and the fluid-structure interaction between the tire and water,the braking process of a grooved radial tire on the wet-road with 10mm depth in a series of discretized speeds were simulated by using the commercial FEM codes-ABAQUS with a discretizd analysis method.Based on each FEM result, the braking time and distance were obtained via correlated analysis method.The comparison with the simulation results of breaking performance between dry-road and wet-road was presented to illustrate the validity of the proposed estimation. |
