Optimized design to improve the function of a magnetic pulse forming device

Abstract

Magnetic pulse forming (MPF) is a plastic deformation method that uses a high intensity magnetic field. Compared to the traditional forming process, this method is simple, and produces better surface quality of the molded product after processing. In this study, we maximized the MPF depth of a molded product using the results of an optimization study. In addition, we determined an optimal coil shape, the electrical energy in the capacitance, and the input voltage to the system. MAXWELL, commercial software, was used to calculate the forming pressure and its distribution induced by the electromagnetic field. MAXWELL was also used to determine the coefficients of approximation equations modeled from the pressure distribution, using the least squares method. Furthermore, the commercial structural analysis software ANSYS, and the commercial statistical analysis software PIAnO, were coupled for an analysis of the optimized design factor to find the maximum forming depth.
