摘　　要：为了进一步探究拉深变形力学行为,尤其是拉深破裂时的规律特点,利用DEFORM-2D有限元软件,对1060铝板和10号钢板进行了拉深变形的数值模拟;还专门进行了各种拉深破裂的工艺试验。通过数值模拟与工艺试验,验证了最大拉深力出现时刻的传统观点,但对其破裂问题有新的补充发现;提出了拉深破裂位置的一种新认识;并描述了拉深破裂发生时的一些规律及力学特点。In order to investigate the drawing deformation mechanical behavior,especially,the fracture characteristics at the time of drawing fracture,by adopting sheet of Al-1060 and steel 10,drawing deformation process is simulated with use of finite element software of DEFORM-2D.And some technical tests of drawing fracture are done.Through the medium of simulating and technical test,traditional views on the happening time of maximum drawing load is verified.Besides,there are more new supplements about drawing fracture question.A new knowledge is put forward on the fracture position.And some mechanical characteristics and law when drawing fracture are described.
