Abstract: The launching process of the interception projectile with electromagnetic(EM) launcher is a dynamic and complex process. It is difficult to analyze the process with analytic method. Dynamic simulation of the EM launcher with pancake coil was completed in this paper using the 2D transient solver of Ansoft software. Mathematical model of the launching process was built firstly. Then the launching process of the EM launcher was simulated. The simulation results were compared with the experimental results. It shows that the simulation results match well with the experimental results.
