Abstract

Optimum forming conditions of electromagnetic tube bulging using direct electrode contact methods are analytically and experimentally investigated. In this paper, the effects of changing the forming conditions such as the length of electrode, the capacitance of capacitor bank and charged energy are simulated by FEM for deformation and forming efficiency, and these results are in good agreement with the experimental ones. The forming mechanism is clarified. As the capacitance of capacitor bank and the length of electrode increase, the amplitude of current waves decrease and the period of current increase. The bulge height is reduced when the electrode length increase, but the forming efficiency increase with the electrode length increasing. The larger the capacitance of capacitor bank, the longer the electrode length, the higher the forming efficiency.
