在物理模拟的基础上 ,研究了板料拉深成形过程中 ,材料的性能参数和工艺参数对板料成形性能的影响 ,着重分析了对多道次拉深成形的影响。结果表明 ,无论是材料性能参数还是材料的工艺参数都对再拉深的影响比对单道次拉深的影响要大得多 ,但两种参数对多道次拉深的影响过程前后是一致的。同时可以看出 ,多道次拉深之间是相互影响的 ,不能割裂开来考虑 On the basis of physical simulation, the influence of the material performance parameters and process parameters on the sheet forming performance during the sheet metal forming process was studied, and the influence on the multi-pass deep drawing forming was analyzed emphatically. The results show that both the material performance parameters and the material process parameters have a greater influence on the redrawing than the single-pass deep drawing. However, the influence of the two parameters on the multi-pass deep drawing is consistent before and after the process of. At the same time, it can be seen that there is an interaction between multi-pass deepening and can not be separated
