Measurement of Electromagnetic Launcher Muzzle Velocity with Induced Voltage of B-Dot Probe

Recently (early 2013), LS-DYNA has released EM module to solve transient electromagnetic-structural coupled problem. The ‘transient’ means that this software is able to consider shape, deformation and movement of objective model. Until now, there is few commercial software what supports electromagnetic-structural coupled transient problem despite of much necessity. Especially, to facilitate the coupled transient problem, LS-DYNA adopts boundary element method (BEM) what does not need air field mesh manually. By supporting this ability, eddy current, induced heating and resistive heating problems in transient can be successfully and easily solved. In this paper, by using LS-DYNA EM, conduct B-dot probe performance prediction as install positions and directions. Also, measrue muzzle velocity of an electromangetic laucher by the probe.
