Research on temperature rise characteristics of electromagnetic launcher
In order to study the loss and temperature rise characteristics of the electromagnetic laun-cher,a dynamic calculation model of the electromagnetic launcher was established based on COMSOL finite element simulation software,and the space-time evolution process of the loss and temperature distribution of electromagnetic launcher was simulated by finite element method.The simulation re-sults showed that the armature would melt during the launching process,and the part of the rail in contact with the armature,especially the part near the edge,underwent a larger temperature rise.The relationship between the size of the excitation source,rail material,rail structure,rail size,and tem-perature variation was established by the proposed model,which provided a reference for the thermal management of electromagnetic launchers.
