中文摘要：

通过电磁V弯成形实验，研究不同电磁参数下2024-T3态铝合金试样成形后V型区最小弯曲半径、V型回弹角度及成形深度等方面的变化规律；同时，对比分析机械V弯试样和电磁V弯试样的形状和表面质量。结果显示，随着放电能量的升高，电磁V弯试件的最小弯曲半径减小，回弹角减小，成形深度增大；电磁V弯成形试件的表面质量明显优于机械V弯成形试件，没有局部橘皮现象及回弹翘曲缺陷；电磁V弯成形试件的V型区外侧显微硬度值，介于原始态2024-T3铝合金和机械V弯成形试件之间。

英文摘要：

Electromagnetic V type bending tests were carried out and the variation of minimum bending radius of V area, V type springback angle and forming depth of 2024-T3 aluminum alloy specimens were studied by change electromagnetic parameters, Al- so, the shape and surface quality of mechanical V bend specimen and electromagnetic V bend specimen were compared and ana- lyzed. It shows that, for 2024-T3 aluminum alloys, with the increase of discharge energy, the minimum bending radius and spri- ngback angel decreased while forming depth increased in electromagnetic V type bending test, And there is neither orange peel de- fect nor warpage springback in the surface of electromagnetic V type bending specimen and its surface quality is significantly better than mechanical V type bending specimen, Also the micro-hardness value of electromagnetic V type bending specimen＇s V type area lateral side falls in between that of mechanical V type bending specimen and original state specimen.
