Open publisher page 1 citations

Abstract

Based on FEM static,the 3D model of the drive axle housing was established in the CAD software Pro/e on the basis of this model,the FEA was simulated in computer under the circumstance of ANSYS to get the results of stress distribution,deformation under the four kinds of constraint.The results show the axle housing meets the strength demand,it is reliable under all kinds of driving conditions,then based on the FEA,to optimize the housing.As the result indicates that the weight of the axle housing was reduced remarkably and the maximum stress in housing approaches its breaking point which boosts the utilization of the material,and the stress distributed reasonably.Relevant norms were summarized about establishing FEA models and relevant analysis and optimization conditions which can make analysis fast,gain useful conclusions.
