摘　　要：现有车身外覆盖件的设计难以实施高效的冲压成形仿真分析。本文通过对比分析市场已推出的典型车型,以轿车侧围外板的A柱、B柱、门槛、后侧窗、加油口盖以及尾灯与后保险杠等关键区域为研究对象,面对产品需求考虑冲压工艺,提出了轿车侧围外板关键区域的设计方法。应用该方法设计了一种轿车侧围外板Catia模型,并进行成形工艺方案分析。通过对轿车侧围外板Catia模型的拉延成形仿真,验证了所提设计方法的可行性。结果表明:所设计的轿车侧围外板拉延成形仿真过程收敛,零件区域成形良好;基于冲压工艺的轿车侧围设计方法可行,具有一定的工程应用价值。Considering that it is difficult to carry out efficient stamping simulation analysis for the design of the existing body exterior panels,this paper takes the key areas of the sedan side outer panel,such as A pillar,B pillar,door sill,rear side window,fuel filler cap,tail lamp and rear bumper,as the research objects,and puts forward a design method for the key areas by comparatively analyzing the typical models in the market as well as considering the stamping process in the face of product requirements.A Catia model of the sedan side outer panel is designed using this method,and the forming process is analyzed.The feasibility of the proposed design method is verified by the drawing simulation of the Catia model.The results show that the simulation process of the drawing forming of the car side outer panel is convergent,and the forming of the part area is good.It is concluded that the side panel design method based on stamping technology is feasible and has certain engineering application value.
