摘　　要：利用有限元分析软件MSC-Superform模拟圆形三通件多向加载的成形过程。通过对多向同步、分步、顺序加载三种不同成形方式的时间-速度图以及加载过程中挤压力曲线的比较,得出了多向分步加载为较佳的工艺方案,并对此进行了模具设计。The forming procedure under multi-direction loading modes of three-way union is simulated by using finite element analysis software MSC-Superform,and by comparing with the time-speed charts of three different forming mode such as multi- direction synchronization,step by step and sequence loading as well as extrusion force curve during loading process,the paper points out that the step by step loading is optimum process,and mould is designed according to the simulation results.
