中文摘要：根据汽车车顶天窗翻边成形过程中出现的回弹缺陷,采用有限元法研究天窗翻边的回弹，在分析各种因素与表面缺陷关系的基础上，对某型汽车车顶天窗零件翻边工艺对比分析研究，获得汽车车顶天窗翻边回弹的补偿规律。为汽车车顶天窗模具设计提供理论依据。
英文摘要： Based on the springback defects appeared in the car sunroof skylight flanging forming process, FEM model method is used to study its springback; Analyzing basing on the relationships between various factors and surface defects, and comparatively analyzing a certain type car sunroof skylight parts flanging process, the springback compensation law is proposed. It provides a theoretical basis for the car roof skylights mold designs.
