摘　　要：针对大型面板的重力变形在整车车型设计和生产过程中易被忽略的问题,用DynaForm对某车型的顶盖进行重力变形评估,并验证软件评估结果与实验结果的一致性.结果表明:DynaForm的模拟结果与实验结果基本符合,零件的重力变形评估意义重大.研究结果对于DynaForm在零件重力变形方面的应用和实际生产具有参考和指导意义.As to the issue that the gravity deformation of large panel is easy to be ignored during the whole car design and production process, the gravity deformation on the roof panel of a type of car is estimated using DynaForm and the consistency between the software estimate results and the experiment results is veffied. The results show that the simulation results of DynaForm is consistent with the experiment results and the component gravity deformation estimate is significant. The study results can provide reference and guidance to use DynaForm in the application of component gravity deformation and practical manufacture.
