To form flat workpiece by the flat spiral coil or conical coil is a typical method of magnetic forming. The analysis of the forming processes consists of the analysis of the electric circuit and the dynamic deformation of the workpiece. The purpose of the electric circuit analysis is to calculate the impulsive magnetic pressure and to apply it to the deformation analysis. By analysing the dynamic response of the coil workpiece system while the working coil being stimulated by intentive impulsive current, the formulas calculating magnetic intensity induced by coil, whirling current on workpiece and its magnetic intensity have been established. And the method for determination of forming load has been given. Then, some characteristic curves of forming load have been obtained to describe its distribution. The computation results are consistent with the conclusion obtained from some relative experiments. Finally, by applying the calculating results of forming load to the deformation analysis, the free magnetic bulging process of sheet aluminium have been predicted successfully.

Sheet metal working by a flat spiral coil, a typical way of electromagnetic forming, has been extensively applied in the practical production. Based on the equivalent electric circuit method for analyzing the discharging process and the numerical model of magnetic pressure, an analysis of the effects of the force energy parameters on the forming process in sheet metal expansion was made by the dynamic incremental non linear elastoplastic finite element method. The expansion height varies with the force energy parameters of the electromagnetic forming system by experimental analysis, but the deforming speed becomes larger and the forming time shortens as the voltage or capacitance increases, which is just the reversal of the inductance. The experimental results showed that the scheme of the present analysis is valid for the prediction of the final shape in electromagnetic forming of flat workpiece. However, in order to obtain a more realistic description of the dynamic deformation fields, some improvement should be made in air damping model.
