摘要
PROBLEM TO BE SOLVED: To provide a method and apparatus for testing dynamic durability of ground coils for superconducting magnetic levitation railways, which does not require large scale testing facilities, enables inexpensive verification tests, allows for continuous application of vibration as a ground coil does not generate heat, and can significantly reduce a test period.;SOLUTION: A method of testing dynamic durability of ground coils for superconducting magnetic levitation railways involves; coupling a ground coil 1 for superconducting magnetic levitation railways to an electrodynamic vibrator 4 with a vibration jig 5 in between using a bolt 3; and applying dynamic vibration using inertial force instead of electromagnetic excitation force such that stress generated in the vicinity of the bolt-coupling section 2 is equivalent to stress generated when electromagnetic excitation force is used.;COPYRIGHT: (C)2014,JPO&INPIT
