Abstract

The launching process of the railgun is simulated and analyzed, the stress and deformation mechanism of the rails and armature are obtained, which is for the safe and continuous launching of the railgun. Using finite element simulation software to establish electromagnetic-stress multi-physical field coupling model. The current and magnetic field distribution, volume force density and stress distribution of the rails and armature are obtained by simulation. The analysis results show that under the action of electromagnetic force, the tension angle of armature tail fin becomes larger, resulting in deformation and pressing rails. The stress and deformation of rails at the position of armature are larger. By analyzing the force and deformation of the rails, it can provide reference for the design and maintenance of the railgun.

Key words： railgun; volume force density; multi-physical field coupling; stress distribution
