| 摘 要： | 基于DYNAFORM动力显式有限元分析软件,将数值模拟技术应用于某盒形件的拉深成形过程,研究了该件的一次拉深成形,不同的毛坯形状、尺寸,以及不同的材料参数对该盒形件拉深的成形极限图、厚度分布、减薄率的影响。研究结果表明:一次拉深成形不能满足成形要求,必须采用多道次拉深;板料1由于尺寸较小而更利于拉深成形;厚向异性系数r值较大的材料,有利于拉深成形。

| Abstract: | The numerical simulation is used in the process of deep drawing of the box part , using dynamic explicit FEA software DYNAFORM,the influence of FLD, the distribution of thickness, and the thinning rate which is worked in the deep drawing process of different kinds of blanks and material parameter is researched. The results show that: the box part can not be produced by only one deep drawing , the blank 1 and the blank with large value r are better. |

| Keywords: | numerical simulation blank shape deep drawing material parameter |
