摘　　要：分析了影响喇叭形灯罩成形性能的主要因素:压边力、凸模圆角半径、板料厚度和冲压速度。借助Dynaform软件对喇叭形灯罩拉深成形进行了单因素分析,得到了合理的压边力、凸模圆角半径、板料厚度和冲压速度的取值范围。采用正交试验方法对以上因素进行了多因素的正交优化分析,得到了最优的参数组合。The main factors affecting the formability of the trumpet shaped lampshade were analyzed, including BHF （blank holder force）, punch fillet radius, sheet thickness and drawing speed. The single factor analysis of deep drawing forming of the trumpet shaped lampshade was performed by using Dynaform software. The value ranges of appropriate BHF, punch fillet radius, sheet thickness and drawing speed were obtained. The orthogonal optimization analysis of multiple factors was performed by adopting an orthogonal experiment method. The best parameter combination was gotten.
