汽车后桥桥架成形模具的设计

摘要

In this paper, it is mainly discussed that CAD model designing ofrear axle bridges and CAE analysis of its forming possibility:(1) generating 3D solid graphic from limited 2D graphic data; (2) restructuring working die surfaces of main forming procedures; (3) emulational simulation taking advantage of CAE technology and actual technique parameters available from cooperation worker, and confirming the forming technique of rear axle bridges.%主要描述汽车后桥桥架的CAD造型设计和成形可能性的CAE分析。从有限的二维图形数据中产生三维的立体图形，然后重构主要的成型工步(前四步)的模具工作型面。利用厂方提供的工艺参数，采用CAE技术进行仿真模拟，对后桥桥架成形工艺确认。
