Popis:	The purpose of this study is to investigate the relation between vibration and heat generation in superconducting magnets (SCMs) for magnetically levitated vehicles, and to determine the SCM structure which reduces heat generation. Thus, two experimental SCMs are designed and produced. First, vibration tests are performed, in which electromagnetic forces due to the ripple magnetic fields from ground coils are applied to the outer vessels of these SCMs. These results clarify vibration modes causing high heat generation in SCMs, i. e., a torsion, a bending, a yawing, and a rolling mode. Second, some eigenvalue analyses involving variation of positions of load supports for an inner vessel are performed, using a simple finite element model. These results are used to determine the optimum supporting method of inner vessels which prevents the resonances with the vibration modes causing high heat generation.
