Abstract

The R&D of Central Solenoid Model Coil is a preparatory stage towards the final fabrication of China Fusion Engineering Test Reactor Central Solenoid. In view of the risk of being tear down or destroyed of the CSMC insulation components and current lead caused by the electromagnetic force, the preload system is designed and mounted around the circumferential direction of the cylindrical coil modules. In order to check the joint resistance, peak magnetic field, AC loss, mechanical performance of preload components under eddy current, CSMC will be tested under several typical current waves. For the sake of safety, a comprehensive mechanical analyses on the preload components need to be carried out before the final commissioning of CSMC. In this paper the magnetic density and eddy current on the preload components are calculated first. Then the electromagnetic force on the preload components under the testing current is analyzed. Finally, the mechanical analysis and stress evaluation are performed. The study presented in the paper will provide reference for the operation of CSMC under the testing current.
