摘要
对汽车轮辋结构进行整体建模,分别对热处理前后的汽车轮辋进行了静结构分析,并利用子模型法建立轮辋应力集中区域的子模型。仿真结果表明:最大应力出现在轮辐和轮毂相连接的倒角处,子模型中汽车轮辋的最大等效应力相对于整体模型升高了约9%;经热处理后轮辋强度有一定的提高,但不明显。
The overall modelling on wheel rim was made, and static structural of wheel rim before and after heat treatment were analyzed, respectively. Submodeling was used to model the region of stress concentration in the wheel rim. The simulation results show that the maximum stresses occur in the fillet where the spoke connects to the hub, and maximum stress in the submodel is raised by about 9% than that in overall modelling. The strength of wheel rim after heat treatment raises to a certain extent, but it is not obvious.
