Problems solved by technology

However, in all current high-temperature superconducting maglev vehicle systems, when placing superconducting blocks on board, they do not consider the relationship between the placement direction of the blocks and the direction of the permanent magnet track, but randomly place them, causing them to capture permanent magnets. The ability of the magnetic track magnetic field is not high, and the magnetic levitation performance needs to be improved

Abstract

The invention discloses a high-temperature superconducting magnetic suspension vehicle system. The high-temperature superconducting magnetic suspension vehicle system comprises a permanent magnet track (1) which consists of permanent magnets, magnetism gathering materials and the like, a suspension vehicle body above the permanent magnet track (1), and a low-temperature container (2) fixed at the bottom of the suspension vehicle body, wherein a single or a plurality of high-temperature superconducting block materials (3) are fixed in the low-temperature container. The high-temperature superconducting magnetic suspension vehicle system is characterized in that the crystallon surface (3a) of the superconducting block materials (3) faces to the permanent magnet track (1), and one crystallon growth border line (3b) of the crystallon surface (3a) is consistent with the extending direction of the permanent magnet track (1). The superconducting block material magnetic suspension vehicle system can obtain stronger and more stable suspension performance under the circumstance that any spare parts and costs are not increased.

Description

technical field [0001] The invention relates to the technical field of high-temperature superconducting applications, in particular to the technical field of high-temperature superconducting magnetic levitation. Background technique [0002] The existing high-temperature superconducting maglev vehicle system includes a permanent magnet track composed of permanent magnets and magnetic gathering materials, a suspended vehicle body above the permanent magnet track, and a cryogenic container fixed at the bottom of the suspended vehicle body. or multiple high-temperature superconducting bulk materials. The levitation principle is that the induced current in the high-temperature superconducting block interacts with the magnetic field generated by the permanent magnet track to generate a repulsive force, coupled with the pinning effect of the high-temperature superconducting block itself, so that the car body can be moved without any control system. It is stably suspended on the p...
