摘　　要：用Dynaform有限元仿真软件对汽车制动器螺旋底外壳件液压拉深成形过程进行了模拟,详细阐述了液压拉深成形仿真技术在制动器外壳件液压成形中的应用具体步骤,分析了压边力和液体压力对阶梯形件成形品质的影响。研究结果表明,合适的压边力和液体压力能防止制动器螺旋底外壳件拉深缺陷的发生。This paper uses the finite element simulation software of Dynaform to simulate the hydraulic deep drawing process of the automobile brake spiral shell, describes the concrete steps of hydraulic deep drawing simulation technology in a hydraulic brake shell forming, analyzes the effect of the blank-holder force and liquid pressure on the quality. The study shows that, the suitable blankholder force and liquid pressure can prevent the brake spiral shell from appearing in the deep drawing defect.
