| Abstract: | A finite element model of PASSAT twist beam rear axle is established. Safety coefficient, static twist rigidity and the first mode are considered as the standard for light weight performance evaluation. Three materials are separately used to optimize the weight of rear axle which is presented in three different kind of structure. In conclusion, the best optimal light weight rear axle is found the basis of a synthetical analysis of performance standard, manufacture process, material price and mass decrease. |
