Abstract
In this paper, the finite element analysis for the design of a high speed forming press
using electromagnetic pulse force has been performed. The punch of the press has been
fixed on a aluminium plate, which is driven by the electromagnetic pulse force. The force
is the repulsive force between aluminium plate and the coil. The coil has been supplied
with a high voltage AC current impulse from the capacitors and then the magnetized
aluminium plate has been forced to move upward with high speed. For the analysis of the
pressing, the coupled analysis of electromagnetic field and rigid-body dynamic of the
aluminium plate has been performed with a commercial FE-software, ANSYS and the
rigid-body dynamics theory.
