摘　　要：以某连接器外壳为研究对象,采用有限元数值模拟和物理实验相结合的方法对多道次拉延成形工艺进行研究。即通过对每道次模拟和实验后制件相应厚度进行对比,总结出多道次拉延工艺成形特点。结果表明:每道次有限元数值模拟的厚度与试验测得厚度相差较小,所以可以通过有限元模拟手段预测多道次拉延成形厚度变化;采用多道次连续拉延成形工艺可以解决总拉延系数比较小的制件拉延成形问题。Taken a connector shell as a example,the multi-step drawing process is studied by using finite element numerical simulation and experiments in this paper.The characteristics of multi-step drawing process are summarized by comparing the corresponding thickness of the simulated and tested parts.It is showed that the thickness of each parts of finite element simulation is less different from that of the test,so the thickness of multi-step drawing can be predicted by means of finite element simulation.The multi-step continuous drawing process can solve the problem of forming parts with small total drawing coefficient .
