摘要：In this article, a high-speed forming press using electromagnetic pulse force is designed with the finite element analysis. The punch of the press is fixed to an aluminum plate driven by electromagnetic pulse force. The force is the repulsive force between the aluminum plate and the coil. The coil is supplied with a high-voltage AC current impulse from the capacitor, and then the magnetized aluminum plate moves upward at high speed to perform the pressing. For the analysis of the pressing, the coupled analysis of electromagnetic field and rigid-body dynamics of the aluminum plate is performed with a commercial finite element software, ANSYS, and the rigid-body dynamics theory. A simple upsetting test is performed with the high-speed press.
