Development of REBCO (Rare-Earth Barium Copper Oxide) magnets has been ongoing with the purpose of reducing the cost of operating maglev trains. On-board superconducting magnets are exposed to severe vibrations due to the varying magnetic field. This paper describes mechanical vibration tests on an actual REBCO coil. The coil was vibrated at 10 G (98 m/s2) by excitation. The heat load due to vibrations was less than 2 W, which is a small percent of the total heat load. In addition, eddy current heating was evaluated with numerical electromagnetic analysis.
