Simulation Study on Mechanical Response of Cambered Surface Armature and Rail Under Electromagnetic and Thermal Loads

摘要

In this paper, an indirect decoupling method is established to simulate the physical process of an electromagnetic launch considering electromagnetic force, thermo-softening of metallic material, and melting interface layer effects. The dynamic responses of cambered surface rail and armature under electromagnetic and thermal loads are analyzed and a simulation method is provided for the engineering applications of electromagnetic launch technology.
