摘　　要：以某离合器端盖为研究对象,基于Dynaform分析软件对带凸缘筒类零件拉深成形过程进行了数值模拟,获得了该类零件在拉深时应变及壁厚减薄率的分布规律,并通过实验验证了有限元模型的合理性。通过比较J31-315B普通压力机与等公称压力的GP2S-S300伺服压力机的滑块运动方式,得出拉深成形时滑块运动方式对制件成形质量的影响规律。结果表明,采用阶梯式滑块运动模式可以有效提高拉深成形质量,降低制件破裂的危险。The deep drawing process of cylindrical part with flange was simulated by taking a clutch-cover as a researching object based on the software Dynaform.The distributions of strain and thickness thinning rate of drawn workpiece were obtained.The rationality of finite element model was verified by experiment.The influence of slide motion mode on forming quality was analyzed by comparing J31-315B conventional mechanical press with GP2S-servo press.It shows that comparing with the deep drawing with conventional mechanical press,the forming quality by staged drawing improves effectively and the risk of fracture decreases significantly.
