VIBRATION CHARACTERISTICS OF SUPERCONDUCTING MAGNETS FOR THE YAMANASHI MAGLEV TEST VEHICLES

On the Yamanashi Maglev Test Line, on-board superconducting magnets vibrate due to harmonic magnetic fields caused by ground coils while vehicles are running. Excessive vibration gives rise to a large heat load and makes it difficult to keep the superconducting state of the magnets. This article describes testing of the superconducting magnets for vibration characteristics under the harmonic magnetic fields by an electromagnetic vibration simulator. In this paper, the results of running tests are compared with those of simulations of the electromagnetic vibration, and the analysis of vibration modes and components are introduced.
