Active electromagnetic armor can enhance defensibility and mobility of the armored vehicles efficiently, which is a promising protection technology of the armor. The working principle of the Interception Projectile Launcher （IPL） in the active electromagnetic armor was analyzed. The dynamics model and the kinematics model of interception projectile were deduced. In order to analyze the movement of interception projectile during the loading, a numerical analysis method for acceleration process of the interception projectile is given. The finite element analysis code was compiled and simulated for the launching process of the interception, the variation of velocity and displacement of the projectile with time was also obtained. We built up an experiment system to verify the simulation result and implemented a launch test. The result showed that the experimental data are well matched with the simulation result.
