You will receive power. In addition, since the ground coils are discretely installed at equal intervals, in addition to the fundamental frequency described above, the harmonic components also vibrate in a complex manner. The vibration of the train running at a constant speed causes the superconducting magnet to vibrate, causing the superconducting magnet to generate heat.

振動を低減させる作用をする。A damping device 10 is installed on the outer tank 8. The vibration damping device 10 includes a pedestal 11 fixed to the inner surface of the outer tub 8, one end in contact with the inner surface of the outer tub 8, and the other end pedestal 11
It is composed of a bolt 12 or a damping plate 13 fixed by welding to an inclined portion of the upper surface. The damping plate 3 is the outer tank 8
Since it is inclined with respect to the inner surface of, the one end thereof is preloaded and is in contact with the inner surface of the outer tub 8. The surface pressure of the damping plate 13 against the inner surface of the outer tub 8 can be adjusted by changing the inclination angle of the pedestal 11.

させる。The superconducting magnetic levitation train levitates by the magnetic force created by the ground coil 4 and the superconducting magnet body 6 installed on the ground. Since the N pole and the S pole of the ground coil 4 change alternately, the superconducting magnet 2 moving on the ground coil 4 receives a fluctuating magnetic field generated by switching the N pole and the S pole. Therefore, a secondary current is induced in the outer tub 8 that houses the superconducting magnet body 6. The induced current and the magnetic field of the superconducting magnet body 6 generate electromagnetic force according to Fleming's law. This electromagnetic force causes the superconducting magnet body 6 to vibrate.

６への伝達を抑えることができる。On the other hand, the superconducting magnet 2 has an extremely low temperature (absolute 4 degrees).
Therefore, it is important to suppress vibrations that may cause heat generation and the like. Therefore, when the magnetic levitation train travels at a constant speed, it receives an electromagnetic excitation force whose basic frequency is a frequency determined by the traveling speed and the installation interval of the levitation coil 4 on the ground. Also, the ground coil 4
Since is installed discretely at equal intervals, it generates an electromagnetic excitation force of its harmonic component in addition to the fundamental frequency described above. Due to this electromagnetic excitation force, the outer tub 8 is excited and vibrates. The vibration generated in the outer tub 8 is transmitted to the superconducting magnet body 6 via the load support 9 and vibrates the superconducting magnet 2 to cause quenching. It is attenuated, and the transmission to the superconducting magnet body 6 can be suppressed.

する。That is, when the outer tub 8 vibrates and is deformed by the electromagnetic force, one end of the damping plate 13 of the vibration damping device 10 and the inner surface of the outer tub 8 contact each other and rub against each other. By the friction at that time, the vibration energy of the outer tub 8 can be converted into heat energy and disappeared, and the vibration can be attenuated. Specifically, when the outer tub 8 has a maximum amplitude in the negative direction, as shown in FIG. 2, and when the outer tub 8 has a maximum amplitude in the positive direction, as shown in FIG. The one end of the damping plate 13 is always in contact with the surface of the outer tub 8 to reduce the vibration of the outer tub 8.
