Simulation analysis of asynchronous induction type coil gun armature structure parameters

Abstract In this paper, the asynchronous induction coil gun is selected as the object of study, and its working principle is firstly briefly introduced, then the mathematical model is established by using the knowledge of electromagnetism, and then the MAXWELL component of ANSYS analysis software is used to simulate the velocity change curve of the projectile in the time domain under different conditions by combining static analysis and transient analysis, which reveals the relationship between the armature The relationship between structural parameters such as armature material, armature axial length, armature position, armature inner diameter and armature outer diameter and projectile end velocity is revealed, and the influence of several structural parameters on the acceleration performance of coil gun launcher is summarized and analyzed, and the optimized design principles of armature are summarized according to the obtained conclusions to provide theoretical references for practical applications.
