Abstract: A mechanical analysis based on ANSYS was carried out for ITER correction coil feeder. According to the feeder structure character, the finite element model was simplified. The Lorentz force on the Busbar was obtained from magnetic analysis, and the support distance of Busbar was ascertained by the EM force. For structural analysis, the EM force was applied as reaction force, different load cases were applied on structural analysis model, and the stress and displacement in different load cases were obtained accordingly. The simulation results indicate that the structural design of feeder is feasible and can fulfill the stress design criterion of feeder.
