The resonance modes of the on-board superconducting magnet for the JR Maglev system actually obtained at the durability test were two (propulsion and levitation modes). To reduce the durability test period of the specimen by half, it was investigated in this study how those two resonance modes were simultaneously reproduced. It appears that those two resonance modes are simultaneously reproducible if the three accelerating points to reproduce its levitation mode are used, and if proper beams to shift the resonance frequencies of its propulsion and levitation modes are added.

The resonance modes of the on-board superconducting magnet for the JR Maglev system actually obtained at the durability test were two in number (propulsion and levitation modes).

It appears that those two resonance modes are simultaneously reproducible if the three accelerating points to reproduce its levitation mode are used, and if proper beams to shift the resonance frequencies of its propulsion and levitation modes are added.
