Abstract：

The phenomenon that electromagnetic force distributions produced by rectangular coil are different with different sheet metal sizes in the electromagnetic forming was studied by experiment and numerical simulation analysis. The electromagnetic-force distributions of sheet metal with large size and small size (size smaller than the rectangular coil size) were obtained by numerical simulation, and experiment of electromagnetic forming on the small size sheet metal was conducted. Different forming results were obtained by changing the relative position between sheet metal and coil under the same sheet metal size and forming voltage. Combining the regularity of the simulation with the experiment, the optimal forming condition of the small size sheet metal is determined in the electromagnetic forming. When the sheet metal is between the peak of two electromagnetic forces of rectangular coil, namely, the relative position between sheet metal and coil is 7 mm~13 mm, the forming result is best.
