为了解决具有异形内轮廓的冲压件翻边工序中易产生裂纹等缺陷，分析了异形内轮廓翻边成形时周向应变分散效应。
In order to solve the lack of flaw when flanging the part with freeform internal profile, the circumferential strain dispersion effect has been analyzed in flanging the profile.
车身零件翻边前一般有修边工序，需要准确的修边线，否则翻边后零件达不到零件尺寸要求。
Before flanging auto-body panels, a feasible trimming line should be obtained, otherwise the final part shape after flanging cannot meet the dimensional requirement.
然而，现今的研究中，相对于冲裁、拉深、弯曲等冲压基本工序而言，关于翻边工艺方面的研究比较少，与翻边有关的文献资料更为有限。
However, compared with other stamping processes such as blanking, drawing and bending, the investigation about flanging process is very limited in existing documents.
