Abstract

The central solenoid (CS) 3L feeder is applied to convey the coolant and electrical energy to the CS as well as house the instrumentation wiring. Due to cryogenic and complex electro-magnetic (EM) environment, CS 3L feeder suffers great thermal contract and huge Lorentz force. This paper aims at investigating the structural design of some key components and mechanical performance of CS 3L feeder. Due to complicated geometry and large scale, the electromagnetic–structural coupling analysis of CS 3L feeder is performed based on loading equivalent transfer principle, the results indicate that the main structure is reasonable, which provides a feasible option for practical engineering consideration. Finally, the further structural optimization, insulation, thermal analysis and seismic analysis are put forward.
