Abstract

This article proposes a novel separable field shaper design for electromagnetic sheet impact forming. The efficiency of the field shaper under different geometric parameters was evaluated through a combination of the Taguchi method and three-dimensional coupled simulation. The deviation in impact velocity between the experiment and the simulation was under 3%. The results indicate that the slit feature determines the performance of the field shaper. Wider slits reduce the energy loss resulting from electromagnetic repulsion. In addition, with more field shaper components, the generated magnetic pressure will be distributed more evenly. Based on the analysis result of the nonsymmetric edge effect, some guidelines for designing the field shaper are proposed.
