    摘要: A method for detecting temperature rise inside a superconducting levitation device based on deep learning is provided. An initial vibration acceleration information, an initial temperature rise information, and a vibration acceleration detection information are obtained. Feature extraction is performed on the initial vibration acceleration information to obtain a high-frequency feature parameter set and a low-frequency feature parameter set. Wavelet band energy calculation is performed for the high-frequency feature parameter set and the low-frequency feature parameter set to obtain a wavelet band energy information. The wavelet band energy information and the initial temperature rise information are input into a preset deep learning network for training to obtain an internal temperature rise detection model of the superconducting levitation device. The detection information is input into the internal temperature rise detection model to obtain an internal temperature rise prediction information to reflect real-time temperature rise of the superconductor.

    摘要: 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.

    摘要: 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.
