发明名称 MAGNETIC LEVITATION TRAIN
摘要 PURPOSE:To provide a magnetic levitation train capable of reducing the vibration of a superconducting magnet. CONSTITUTION:An auxiliary coil 13 is provided, which acts in such a manner that the magnetic field generated by a superconducting coil 9 can be controlled when a superconducting magnet is resonant to a superconducting magnet constituting a magnetic levitation train. By doing this, resonance can be eliminated by changing the natural frequency possessed by the superconducting magnet after the occurrence of the resonance of the superconducting magnet in running state, thereby reducing the vibration.
