摘　　要：行李箱内板是汽车覆盖件中的重要零件,生产中为了减轻汽车重量,可采用高强度钢板来成形。在板料成形基本理论的基础上,以高强度钢TRIP600为材料模型,采用有限元软件DYNAFORM对汽车行李箱内板拉深过程进行了模拟,获得了成形后的零件壁厚变薄率分布图、成形极限图和对称面的回弹值。结果表明,汽车行李箱内板在拉深过程中不易破裂,但容易出现起皱和回弹缺陷,形状冻结性差。该结果对提高汽车行李箱内板拉深件的成形质量具有重要的指导意义。Trunk lid inner panel is an important part used in auto panels. In order to lighten the automobile＇s gravity, high strength steel sheet is generally used. Based on the principal theory of sheet metal forming, the deep drawing of trunk lid inner panel was simulated by finite element software DYNAFORM with TRIP600 high strength steel sheet as material model. The part wall thinning rate distribution, forming limit diagram and the rebound value of symmetry plane were obtained. The result shows that it is difficult to produce crack, but prone to produce wrinkling and springbavk in deep drawing of trunk lid inner panel. The study provides a significant guidance to improve the forming quality of the deep drawing parts of trunk lid inner panel.
