Numerical and Experimental Investigation of Inward Tube Electromagnetic Forming- Electromagnetic Study

Abstract:

A numerical simulation of high-speed forming of tubes on the die in electromagnetic forming (EMF) system is presented to study effects of some electromagnetic parameters. Simulations of electromagnetic and structural parts of EMF process are carried out. Calculated currents in this process are in agreement with experimental results measured by Rogowsky coil. But calculated and simulated currents at first peak are a little more than the experimental value. Effects of material and process parameters on bead depth are investigated in detail with this validated code. It deduced that shape of the bead is affected by discharge voltage and coil parameters. As a result, the bead depth increases with the increase of the discharge voltage and decrease of number of windings.
