基于有限元分析的轿车后桥疲劳寿命预测

Fatigue Life Prediction of Car’s Rear Axle Based on FEM Analysis

利用实测道路载荷时间历程 ,结合后轿有限元模型和材料属性 ,用LMSFALANCS软件来预测轿车后桥的疲劳寿命 。

Based on the load history acquired by road test,in combination with Finite Element(FE)models of car's rear axle and material properties, the fatigue life of car’s rear axle is predicted by using LMS FALANCS. The analysis results coincide with the road test very well.
