The temperature of the rail is increasing in a short period of time by the Joule heat generated by the high current passing the contact surface between the rail and the armature, the frictional heat generated by the armature’s movement on the rail surface during the electromagnetic launching process. The launch performance is affected by the surface temperature of the track sharply increases and a decrease in the mechanical performance of the rail. The rail temperature simulation model and tests of the model is established by launch experiments. The model is modified and improved to provide support for the optimization design of thermal management system.

摘要

The temperature of the rail is increasing in a short period of time by the Joule heat generated by the high current passing the contact surface between the rail and the armature, the frictional heat generated by the armature’s movement on the rail surface during the electromagnetic launching process. The launch performance is affected by the surface temperature of the track sharply increases and a decrease in the mechanical performance of the rail. The rail temperature simulation model and tests of the model is established by launch experiments. The model is modified and improved to provide support for the optimization design of thermal management system.
