When using traditional methods to analyze drive axle housing is time-consuming, laborious to corresponding modal analysis is complicated, the deformation calculation is more difficult, so in recent years, the automobile enterprises and the corresponding researchers, both for drive axle housing is modeled by the software, then the modal analysis, using the finite element method analysis of drive axle housing, calculation, so as to get more accurate results. This thesis mainly by using UG software to establish three-dimensional model of the drive axle housing, using ANSYS software to generate finite element model, and then statics analysis of the bridge housing strength and stiffness analysis result, put forward the improvement plan, optimize the structure of bridge housing; Modal analysis, respectively, often prestressed modal analysis, size analysis and generate bridge housing in the first six order modal modal analysis under the cloud, the intrinsic characteristics of the bridge housing, so as to avoid the bridge housing resonance, and the bridge hou
