摘　　要：用DYNAFORM有限元仿真软件对深盒形件液压拉深成形过程进行了模拟,分析了压边力和液体压力对盒形件成形质量的影响。研究结果表明,合适的压边力和液体压力能控制盒形件拉深缺陷的发生,采用液压拉深盒形件可获得更好的壁厚分布。The drawing process for hydroforming a deep rectangular box was analyzed by using finite element simulation software DYNAFORM, and the effect of blank holder force and liquid pressure on the forming quality was researched. The result indicates that proper blank holder force and liquid pressure will help to reduce the occurrence of drawing defects and the application of hydroforming can get more uniform wall thickness.
