Characteristic Analysis and Verification of Electromagnetic Force for Armature of the Electromagnetic Rail Launcher

In this paper, the armature electromagnetic force of the electromagnetic rail launcher is taken as the research object, and the electromagnetic field control equation considering the influence of armature movement velocity and the armature dynamic equation considering the influence of resistance are given. Then, the finite element calculation model of the electromagnetic rail launcher is built, and the correctness of the model is verified by data comparison. Finally, the trapezoidal excitation current is used to further analyze the dynamic characteristics of the armature electromagnetic force under the influence of different factors. The research results have important guiding significance for the study of the dynamic characteristics of the electromagnetic rail launcher under the actual working conditions and the refined design of the pivot rail structure.
