Abstract：

Electromagnetic forming has the characteristics of large impact load and high efficiency. For aluminum alloy 2024 integral panel, a series of experimental researches were carried out by a new method of local-loading electromagnetic forming. The influences of some process parameters such as loading distance, discharge voltage, plate thickness and constraint condition on the bending deformation of the aluminum alloy plate were analyzed. The results show that reasonable selections of loading distance, discharge voltage and plate thickness are critical to the deformation of flat plates. The deformation degree of metal plates increases obviously with the increase of loading distance, and the contour is smooth. However, the loading distance should not exceed a certain value. The deformation degree of metal plates also increases with the increases of discharge voltage and plate thickness within a certain range. After the constraints being removed, the bending deflection becomes larger, and residual stress has a greater impact on the bending deflection than thickness reduction.
