Abstract

Coupling behaviour is analyzed between structural vibration and eddy currents in a superconducting magnet for magnetically levitated vehicles. The complicated coupling behaviour between them is clarified using a new analysis method prepared previously. Calculations considering the coupling effect show that Joule losses in the inner vessel due to eddy currents induced by structural vibration in resonance are very different between the bending and torsion modes
