VACUUM PIPELINE HIGH-TEMPERATURE SUPERCONDUCTING MAGNETIC LEVITATION HIGH-SPEED TEST PLATFORM AND TEST METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/087734
Kind Code:
A1
Abstract:
A vacuum pipeline (15) high-temperature superconducting magnetic levitation high-speed test platform and a test method thereof, relating to the technical field of magnetic levitation. The test platform comprises a vacuum pipeline (15), a support platform, a model vehicle (1), and a portal frame (8). The support platform is arranged in the vacuum pipeline (15), and the support platform is provided with a permanent magnet track (7) and stator windings (13); a mover (3) and a cryogenic Dewar (5) are provided at the bottom of the model vehicle (1), a superconducting block material is provided in the cryogenic Dewar (5), and the side walls of the model vehicle (1) are made of a metal material; the portal frame (8) is arranged on the support platform, and permanent magnets (9) are provided on columns of the portal frame (8). By accelerating the model vehicle (1) to 400km/h and above, exploration of the levitation and guidance performance of high-temperature superconducting magnetic levitation is correspondingly carried out, research on a high-temperature superconducting magnetic levitation vehicle-track coupling action mechanism and dynamic stability, a high-temperature superconducting magnetic levitation vehicle-track-pipeline magnetism-electricity-force-gas multiphysics dynamic coupling mechanism and model, and the dynamic characteristics during trains on double tracks passing each other is carried out, and research on the levitation, guidance and aerodynamic characteristics of a high-temperature superconducting magnetic levitation vehicle in a low air pressure environment is also carried out.
