对两种不同截面的铝型材分别在6种不同拉弯成形工艺中的拉弯过程进行有限元数值模拟,探讨成形工艺、弯曲半径与型材截面形状对拉弯成形后型材回弹的影响。
The finite element numerical simulation of the bending process of two kinds of aluminum profiles with different cross sections in six different bending and forming processes was carried out. The effects of forming process, bending radius and cross section shape on springback of profile after drawing and bending were discussed.
