摘　　要：采用圆形拉延筋、矩形拉延筋和拉延槛优化了大型薄壁封头的成形工艺。利用有限元软件和正交试验设计确定出?3000 mm×10 mm的椭圆形封头拉延筋类型和参数,并采用多目标优化法得出最优的拉延筋参数组合。试验结果表明,使用拉延筋可以将传统三次成形缩短到一次,从而有效地缩短封头生产时间,提高生产效率。The forming process of large thin-wall head was optimized by using the round draw-bead, the rectangular draw-bead and edge-bead. The type and parameters of the draw-bead of ？3000 mm×10 mm ellipsoidal head were ascertained by using finite element software and the orthogonal experiment design. And the best parameter combination of the draw-bead was obtained by using the multi-objective optimization method. The experimental results show that using the draw-bead can reduce forming procedure from the traditional three steps to single pass. Thereby, production time of the head is effectively reduced and productivity is increased.
