摘　　要：以某型号药用铝3003瓶盖为研究对象,针对瓶盖顶部凸环内壁处拉深变薄率较高,生产中拉裂安全裕度不够的问题,通过将正交试验设计与冲压数值模拟相结合应用的方法,以ABAQUS有限元软件为仿真优化平台,综合评估了冲压过程中的压边力、坯料直径、凹模圆角和模具间隙等参数对冲压件冲压成形质量的影响;通过对仿真数据的极差分析和工艺分析,确定了优选的工艺参数组合。实验表明,基于正交试验对瓶盖成形工艺参数和结构参数优化的方法可行,所得结论对拉深工艺的设计具有指导意义。Apharmaceutical bottle cup made by aluminium alloy 3003 was taken as study object. To reduce the high thinning rate of bulge loop inner wall on the cap top, orthogonal experiment and stamping numerical simulation werecombined. A comprehensive assessment about the influence of the stamping process parameters, such as blank holder force, friction coefficient, die clearance, blank diameter, die radius and other parameters of mould, was acquired. Then, according to range analysis and process study, the optimized process values were obtained. Finally, the cup was formed basing on the optimized result and the experiment conclusion showed that the result was available.
