Abstract
oday progress in railgun research is usually achieved
experimentally with support from static simulations. It is of great
interest to set up dynamic simulations that allow to asses time
dependent information about the parameters involved in the elec-
tromagnetic acceleration of masses. In this investigation a dynamic
3-d finite element simulation of a small, 28 mm caliber railgun was
implemented. The novelty of this approach is, that after a simulation
run, the time history of, for example the velocity of the projectile is
available. To validate the simulation results, a series of shots with a
28 mm caliber railgun was performed. Good agreement between the
experiment and the dynamic simulation was observed.
