采用基于坯料形状变化灵敏度分析的方法 ,自行开发坯料形状优化计算程序 ,并利用LS -DYNA3D软件进行模拟计算 ,确定非轴对称拉深件成形时坯料的最优形状 ,可经较少的迭代次数取得比较满意的计算结果
The billet shape optimization calculation program was developed based on the change of sensitivity of billet shape. The LS-DYNA3D software was used to simulate and calculate the optimal shape of the billet during forming, which can be achieved with fewer iterations Get more satisfied with the calculation results
