Abstract
In this paper, using the differential equation of the armature motion for the electromagnetic Railguns, influences of the driving current distribution on the velocities of the projectile are investigated. Several kinds of the typical energy losses are considered. The influences of the driving current distribution on the transfer efficiency of the railgun system are analyzed. For a given exit velocity of the projectile and rail length, a proper relative time ratio of the pulse currents is determined which corresponds to the optimum system transfer efficiency. The results can be used to design pulse current distribution of the railgun system.
