る。Next, the operation of the conventional superconducting magnet device 1 will be described. The superconducting magnet device 1 during traveling makes the vehicle 2 levitate in the vertical direction and propels it in the longitudinal direction by the electromagnetic force acting between the superconducting coil 11 and the levitation / guidance coil 5 and the propulsion coil 6 on the ground side. And guide in the left and right directions. At this time, a large electromagnetic force is generated between the superconducting coil 11 and the levitation / guidance coil 5 and the propulsion coil 6 in the up-down direction, the front-rear direction, and the left-right direction. Rib 1 from 11

The superconducting coil 11 exhibits the function of superconductivity in the state where it is cooled by the liquid helium 12. On the other hand, the liquid helium 12, which is the refrigerant, evaporates due to heat input by heat conduction from the fixed shaft 8 to the heat insulating support 9 and heat generation during traveling.
Then, the evaporated portion is liquefied by a refrigerator (not shown) mounted on the bogie frame 3. Therefore, it is possible to continuously run without replenishing the refrigerant from the outside.

で表して内槽１０の振動モードを示している。The external force that the superconducting magnet device 1 receives while traveling is roughly classified into two types.
One of them is a levitation force for levitation of a vehicle body that acts steadily in the vertical direction, a guide force for guiding the vehicle body in the left-right direction, and a propulsion force for propelling the vehicle body in the front-back direction. The other is a fluctuating load depending on the traveling speed that occurs because the levitation / guide coil 5 and the propulsion coil 6 are installed at equal intervals in the traveling direction of the vehicle. Among them, the fluctuating load that depends on the traveling speed is an AC component, and its frequency increases in proportion to the traveling speed. The external force acts on the superconducting coil 11, and acts on the inner tank 10 from the superconducting coil 11 via the rib 15.
It is transmitted from the inner tank 10 to the bogie frame 3 via the heat insulating support 9 and the fixed shaft 8. Then, an oscillating force such as bending and twisting is applied to the inner tank 10 and the superconducting coil 11 due to the variable load. Then, when a large number of natural frequencies of the inner tank 10 and the superconducting coil 11 match the frequency proportional to the traveling speed and a resonance state is reached, the inner tank 10 and the superconducting coil 11 are vibrated greatly. The vibration of the inner tank 10 is shown in FIG.
Rolling vibration as shown in FIG. 4, yawing vibration as shown in FIG. 15, and torsional vibration as shown in FIG. 14 to 16, the racetrack-like shape of the inner tank 10 is simplified and represented by a line to show the vibration mode of the inner tank 10.

Although it is transmitted to the pipe 18 through the bellows 17, the pipe 1
8 is firmly fixed to the outer tub 7 etc., so the bellows 1
Relative displacement through 7 will occur. Due to this relative displacement, frictional heat is generated, and liquid helium 12 which is a refrigerant is
Increase the amount of evaporation. Then, if the amount of evaporation becomes abnormally large, the amount of liquid helium 12 that is not liquefied and recovered by the refrigerator increases, and the amount of liquid helium 12 in the inner tank 10 becomes insufficient, so that the superconducting state of the superconducting coil 11 cannot be maintained. There was a problem that the car could not run.

実施の形態５と同様に構成されている。Embodiment 7. 9 is a side view showing a magnetic levitation type superconducting magnet device for a vehicle according to Embodiment 7 of the present invention. In the seventh embodiment, the inner tank 10 is heat-insulated and supported by the outer tank at four locations on the inner circumference side via the heat-insulating supports 20 and 20a, respectively, and the four locations on the outer-corner side corner portions are respectively heat-insulating supports 21, 21. The outer tank is adiabatically supported via 21a. Further, the four heat insulating supports 20 and 20 a are installed at positions symmetrical with respect to a horizontal plane passing through the center of the inner tank 10 and a vertical plane. Similarly, the four heat insulating supports 21 and 21a are also installed at positions symmetrical with respect to a horizontal plane passing through the center of the inner tank 10 and a vertical plane. The heat insulating supports 20a and 21a are formed to have a smaller outer diameter than the heat insulating supports 20 and 21 to reduce the spring constant.
Therefore, in this Embodiment 7, the inner tank 10 is
Adiabatic supports 20, 20a, 2 arranged symmetrically with respect to each of a horizontal plane and a vertical plane passing through the center of
Although it is heat-insulated and supported by the outer tank via 1 and 21a, from the viewpoint of the spring characteristics of the heat-insulating support, the outer tank is heat-insulated in a support relationship that is asymmetric with respect to the horizontal and vertical planes passing through the center of the inner tank 10. You will be supported. Furthermore, the heat insulating support 2
0a and 21a are the rotation center of the yawing vibration of the inner tub 10 and the inner tub 10 caused by the asymmetrical support relationship with respect to the vertical plane passing through the center of the inner tub 10 from the viewpoint of spring characteristics.
The spring characteristic is set so that the center of rotation of the rolling vibration of the inner tub 10 caused by the asymmetrical support relationship with respect to the horizontal plane passing through the center of the ∘ is substantially matched. The pipe 16 is connected to the inner tank 10 at a position where a vertical plane passing through the center of rotation of yawing vibration and rolling vibration and the outer peripheral surface of the inner tank 10 intersect. The other structure is the same as that of the fifth embodiment.

も、上記実施の形態４と同様の効果が得られる。In the seventh embodiment, the yawing vibration and rolling vibration of the inner tank 10 caused by the external force applied to the superconducting magnet device during traveling are caused by the pipe 16 and the inner tank 1.
The position close to the connection part with 0 becomes a vibration mode which becomes a node of vibration. Therefore, the vibration of the pipe 16 caused by the yawing vibration and the rolling vibration of the inner tank 10 is suppressed, and the bellows 17 between the pipe 16 connected to the inner tank 10 and the pipe 18 firmly fixed to the outer tank 17 is suppressed. Since the relative displacement via the contact is suppressed to be small, the same effect as in the above-described fourth embodiment can be obtained in the seventh embodiment.

Instead, it is only necessary to satisfy the arrangement condition of the heat insulating support in each of the embodiments.
