摘要
针对传统的毛坯展开方法所存在的问题 ,本文采用形变理论并利用理想形变的假设 ,导出用于板料成形设计的逆算法。理想形变假设认为变形是在整体塑性功取得相对极值的条件下得到的 ,文中给出了理想形变的数学公式和有限元表达。将此数值方法的结果与实验数据对照 。
In order to solve the problem in traditional method of blank development,deformation theory and the assumption of ideal forming are adopted,and one step approach to design sheet metal forming is derived Mathematics formula and FE expression of ideal forming,which is obtained when the global plastic work has its relative extreme value,are provided Compared with experiment results,the result obtained with one step calculation could be acceptable
