Summary

Following completion of the Yamanashi Maglev Test Line, running experiments commenced in the Spring of 1997. By utilizing a superconducting magnet loaded on the vehicle, the eddy current flows by being exposed to the fluctuating field from the ground coils. In addition, the field of the superconducting coil influences the eddy current and the magnetic force generates vibration. Vibration generates heat and generated heat has to be compensated with helium evaporation. To evacuate this drawback, Hitachi, Ltd. has achieved, firstly, the suppression of both vibration and the eddy current by structural optimization through numerical analysis, and secondly in accommodating the amount of helium evaporation within the specified value. By developing a peculiar insulating method, the ground coil attained the specified performance.
