  • Patent number: 11488754
    Abstract: The present invention discloses a superconducting bulk cooling apparatus and cooling method for a high-temperature superconducting magnetic levitation vehicle. The superconducting bulk cooling apparatus for the high-temperature superconducting magnetic levitation vehicle includes a refrigerating machine, a vacuum box and a Dewar tank. A condensing tank is arranged in the vacuum box, and the condensing tank is communicated with the Dewar tank through a nitrogen siphon pipe and a liquid nitrogen return pipe; a heat exchanger connected with the refrigerating machine is arranged in the condensing tank; and a flexible isolation pipe for thermally insulating and isolating the nitrogen siphon pipe and the liquid nitrogen return pipe is connected between the vacuum box and the Dewar tank. The present invention pumps the phase-change nitrogen out of the Dewar tank through a siphoning effect, so that the immersion cooling of high-temperature superconducting bulks is separated from the re-condensation of the nitrogen.

  • Patent number: 11366038
    Abstract: A vibration test bench for electrodynamic-suspension magnetic levitation trains and a testing method using the same. The vibration test bench includes an adjustable track mounting surface, a track base, a guiding track and a simulated levitation device. The track base includes a first track base and a second track base. The first track base and the second track base are respectively provided at two sides of the adjustable track mounting surface. The guiding track is arranged at a bottom of the track base and can be embedded in the T-shaped bolt mounting grooves on the adjustable track mounting surface to move. The simulated levitation device is arranged on the track base and is configured to levitate the magnetic levitation train between the first track base and the second track base.

  • Publication number: 20220115965
    Abstract: This application relates to simulation equipment, and more particularly to an apparatus and method for simulating a line running state of magnetic levitation. The apparatus includes a levitation-guidance mechanism, a moving mechanism and a magnetic guideway fluctuation simulated mechanism. The levitation-guidance mechanism is configured to detect a force on a single Dewar of a maglev train to be simulated. The moving mechanism is configured to move the levitation-guidance mechanism. The magnetic guideway fluctuation simulated mechanism is arranged below the levitation-guidance mechanism, and is configured to apply a variable force to the levitation-guidance mechanism. The variable force is configured to simulate a constantly-variable electromagnetic force applied to the levitation-guidance mechanism by a real track.

  • Publication number: 20220089196
    Abstract: A levitation, propulsion and guidance integrated magnetic levitation system and an improvement method of levitation and guidance. The system includes a maglev train and a maglev track. The maglev train is provided with a permanent magnet array. The maglev track is provided with a driving device and a levitation driving device in sequence along a running direction of the maglev train. An iron plate is arranged in the middle of the maglev track. The driving device accelerates the maglev train from 0 to take-off velocity. The levitation driving device provides a driving force and a levitation force for the maglev train. The iron plate enables the centered running of the maglev train.
