3、he three-dimensional modeling including the development of CAD/CAM/CAE, basic skill about Pro-E, and its concept 、methods all made a detailed explained. Then refer the structure trait of its similar manufacture, thread the exercise of the three-dimensional modeling in fact, based on the three-dimens

4、ional modeling about the drum brake and its parts, assemble them , ultimately build the drum brake assembly. In the basic ,use the Pro/E modeling software and the Pro / mechanical analysis software on the three-dimensional modeling of Wheel Cylinder, make the finite element analysis about stress and emergency of the caliper cylinder bore and educe the result, by appraising, the result accord with the natural demand of use. The key wordThe key word： drum brake three-dimensional modeling fin
