【Abstract】 In this paper a systematic method based on shape sensitivity analysis is proposed and the calculation program for optimizing blank shape for deep-drawing is developed.And the simulation calculation is carried out by using LS-DYNA3D software,the optimum blank shape for non-axisymmetric deep drawing is defined with a few times of iteration.更多还原
