| 摘 要： | 针对铝合金车轮动态弯曲疲劳问题,建立了车轮弯曲实验的静态有限元模型,然后使用商用有限元软件LS-DYNA的隐式计算方法,对铝合金车轮在弯矩作用下的应力分布进行了仿真分析.通过对四个典型状态下车轮主应力分布情况的仿真结果评价,确定了铝合金车轮上最易导致疲劳裂纹产生的高应力区域.该计算机模拟实验平台的建立对铝合金车轮的前期设计开发具有重要的指导意义.

| Abstract: | A finite element model of static bending test of A-alloy wheel is established,based on the wheel dynamic bending fatigue problem.The bending process is simulated by the commercial finite element software LS-DYNA.By analyzing the simulation results of the 1st principle stress distribution in the wheel under different states,the most dangerous area is found where some fatigue cracks would generate easily.It is proved that finite element models of the A-alloy wheel bending test have guiding significance for pr... |
