Optimization of automobile rear axle housing based on response surface approximation model

  • Received Date: 2017-07-05
    Accepted Date: 2018-01-02
  • In order to improve the design strength and fatigue life of the automobile rear axle housing and further improve the vehicle performance, ADAMS was used to establish the vehicle dynamics simulation model,finite element mesh generation was made by combining the three-dimensional model of axle housing material and unit type.ABAQUS was used to carry out finite element statics analysis of the automobile rear axle housing according to Bump working condition, and response surface approximation model was used to optimize the automobile rear axle housing. The results showed that the maximum stress of the rear axle shell under extreme conditions of Bump was reduced by about 10% and the fatigue life was prolonged by about 17%.
