摘　　要：轮胎花纹块接地压力分布对轮胎耐磨性能,抓地性能有着重要的影响。本文利用三维有限元软件,以花纹块表面的节点坐标为设计变量,以花纹块接地压力偏度值为目标函数对花纹块表面形状进行优化。结果表明,该方法可以优化花纹块接地压力,改善轮胎磨损性能和抓地性能。The contact pressure distribution of the tire tread block has an important impact on tire wear re-sistance and grip performance. In this paper, a new optimization procedure to design the surface of tire patterns is combined with 3D finite element method. The coordinates of the nodes of the surface of the tread blocks were chosen as the design variables, and the deviation of contact pres-sure distribution was selected as target variable. The results confirmed that the optimization technique could lead to a final optimum distribution of contact pressure and better wear and grip performance.
