The Finite Element Analysis of Car's Rear Axle and Prediction of Fatigue Life

This paper makes a static strength calculation and fatigue life prediction of a car's rear axle. To find out the dangerous stress and strain points of the bridge shell by making calculation analysis of the structure strength and stiffness of the rear axle bridge shell by using finite element analysis software, MSC.Patran and MSC.Nastran. Using MSC.Fatigue software on the rear axle to make an analysis of its fatigue life base on the finite element analysis, and make a modal analysis with MSC.Nastran software.
