针对无凸缘圆角半径较小的低盒形件,在经验作图法的基础上,提出两因素实验优化设计方法,以关键点的高度均方差作为优化的目标函数。对每个因素和水平采用Dynaform软件进行模拟,并根据目标函数确定最优的水平。模拟和实验结果表明,两者数据基本一致,两因素实验优化设计方法明显的减小了零件圆角区域成形高度的波动范围,较好的改进了浅拉深产品的成形效果,对同类产品的生产具有一定的参考意义。 Based on the empirical mapping method, a two-factor experimental optimization design method is proposed for the low box-shaped parts with small flange radius. The height-mean square deviation of the key points is taken as the objective function of optimization. Dynaform software was used for each factor and level to simulate and determine the optimal level based on the objective function. Simulation and experimental results show that the two data are basically the same, the two-factor experimental optimization design method significantly reduces the forming part of the fillet area height fluctuation range, better improved shallow drawing product forming effect of similar products Production has a certain reference value.
