In the MAGLEV system, trains are operated by the electrodynamic suspension force between ground coils and on-board superconducting magnets (SCMs). During the train running, SCMs are vibrated by the electromagnetic disturbance which is caused when the train passes over ground coils. This phenomenon increases the heat load in the SCM cryogenic equipment. In this study, mechanical heat loss inside the inner vessel was investigated as one of the phenomena which increases heat load in the SCM. The mechanical SC coil vibration test was performed for to evaluate a relation between heat load increases and SC coil vibrations. The heat generation area inside the inner vessel was evaluated by FEM structural analysis which was based on the assumption that the calculated strain at the surface of the SC coil shows the frequency of microscopic slips between the coil fasteners and SC coil. This paper reports the results of vibration test, FEM structural analysis, and consideration of relation between these two results.
