Electromagnetic Field Analysis on Aluminum–Steel Intercepting Plate in the Active Electric Armor

The active electric armor will play an important role in the future of armored vehicle protective systems. The active electric armor interceptor based on the principle of a single-stage coil launcher must use nonmagnetoconductive material, such as aluminum as its inductive coil. However, in order to enhance the interception effectiveness, people hope to use high-strength magnetoconductive material, such as steel. So, the best possible way is to synthesize the two kinds of materials in actual applications. In this paper, the electromagnetic field characteristics and the force acting on the interceptor are described. The analysis of the 3-D eddy current field shows that the thrust force not only did not decrease, but it increased a little when the high-strength magnetoconductive was added. The results of the experiments verified the correctness of the simulation analysis
