Abstract In the successive progress of the rail accelerator, too high local temperature rise in the rails will seriously affect its structural strength, it is necessary to analyze it’s temperature and cooling. Begin with the analysis of the dynamic characteristics of the rail accelerator, the key problems such as the heat source loading of the rails and the time step difference of multiple accelerations were solved. Based on programming of ANSYS-APDL, the electromagnetic-fluid coupling simulation analysis of rails’ cooling was realized. Without Water Cooling, after 5 successive accelerations the maximum temperature of the rails has exceeded the copper softening temperature by 400℃.By analyzing the sensitivity of the cooling water parameters to the cooling effect, the 50% volume concentration of ethylene glycol water solution was selected as the cooling solution. After 7 consecutive accelerations, the maximum temperature of the cooling solution and the rails do not increase, and the highest temperature of the rails is 308.7℃, which do not exceed the softening temperature of the copper material. The simulation method and results can be used to guide the thermal management of the rail accelerator.

Key words： Rail accelerator cooling coupling fields finite element
