In allusion to traditional design method’s malpractice and have advanced technology’s application in mind and try hard to design automobile driving axle housing by means of CAD/CAE method. The article is based on YUEJING Group’s NJ1040 driving axle housing. On one hand, The author has built driving axle housing’s 3D computer model through software Unigraphics NX2.0，on the other hand, in order to review its deflection、intension and rigidity, the article has realized its static and modal analysis. The result makes clear that driving axle housing’s static intension is enough under 2.5 times fully dynamic loaded, and all performance indexes satisfy state standard. At last, the article makes elementary optimize design according to analyzing result, reduces the driving axle housing’s weight, retrenches its material and depresses the manufacture cost. Therefore, the analysis will establish a foundation for further optimize assay by the holy poker.
