摘　　要：运用弹塑性力学原理,提出了半球形件冲压过程的力学模型,给出了非线性的有限元法的数值模拟计算方法。对半球形件冲压的过程实现了数值模拟,并对冲压中一些重要参数进行了研究,为冲压模具设计和工艺参数确定提供了依据。The mechanistc model of drawing of hemisphere- shaped part and the simulating calculation of non - linear finite - element method with the elastic - plastic mechanistic theory are studied. The simultation of the whole process of press forming is carried out. Some key parameters are calculated. The results provide basis for the die design and the determination of the technological parameters.
