摘　　要：利用Dynaform软件模拟连结法兰盘在圆孔翻边成形过程中起皱、孔口边缘最小厚度以及成形高度随压边力变化的规律。结果显示:按照理论计算的压边力模拟成形时,成形高度较大,起皱严重;增大压边力,没有起皱产生;但是随着压边力的增大,成形高度随之减小,而孔口边缘的最小厚度没有太大变化。In this paper,the law of the wrinkling,the minimum thickness and the forming height of the connecting flange in the process of hole flanging process is analyzed by the Dynaform software.The results show that,when the blanking force is simulated according to the theoretical calculation,the forming height is high and the wrinkling is serious.When the blanking force is increased,no wrinkling occurs.However,with the increase of the holder force,the forming height decreases,and the minimum thickness at the edge of hole does not change much.
