While a magnetically levitated vehicles (Maglev) are in motion, the superconducting magnets (SCMs) are vibrated by various disturbances. The main disturbance is the vibration caused by the magnetic field fluctuation, which arising from the ground coils. The heat load and vibration characteristics under these conditions have been evaluated by the electro-magnetic disturbance test which are to simulate actual running conditions. The vibration of the inner vessels are separated into rigid and elastic vibration modes by using least squares method. The mechanical heat load is calculated by the heat load characteristics of both magnetized with the rated magnetomotive force and nonmagnetized. The mechanical heat load has been estimated by considering the acceleration of the inner vessels and the heat sensitivity coefficient.
