摘　　要：采用Autoform/Dynaform软件对汽车后盖内板进行了可制造性仿真分析。研究了不同结构后盖内板的成形性和角部的重力变形量。结果显示,不同结构的后盖内板,虽然成形性均能满足要求,但实际零件的形状有差异。后期产品验证表明,仿真模拟结果与实际生产结果较为一致。The manufacturability of auto deck lid inner was emulation analyze using an Autoform /Dynaform software .The formability and gravity-induced deformation in corner portion were investigated for the deck lid inner of different constructions .The results show that the actual deck lid inners of different constructions differ in shape although their formability fulfills the requirement .Verification of finally made deck lid inners indicates that the simulated result is basically consistent with the actual production result .

关 键 词：成形性 重力变形 后盖内板
