The invention discloses a vehicle double-layer high-temperature superconductor magnetic suspension system, which is characterized by comprising a track and a low-temperature container, wherein the track is made of permanent magnet, a magnetic flux gathering material and the like; the low-temperature container is fixedly arranged in a vehicle body frame; and a high-temperature superconductor layer is fixedly arranged in the low-temperature container and is designed into two layers which are formed by overlapping a lower layer block 103a and an upper layer block 103b. According to the vehicle double-layer high-temperature superconductor magnetic suspension system, by additionally arranging the upper superconductor layer, the aim of simultaneously increasing the suspension force and the guidance force performance of the original single-layer suspension layer can be fulfilled; and the vehicle double-layer high-temperature superconductor magnetic suspension system can be used for optimizing the conventional single-layer high-temperature superconductive magnetic suspension system and improving the load carrying capacity and the stability performance of a superconducting maglev train.
Description
technical field [0001] The invention relates to the technical field of high-temperature superconducting magnetic levitation, in particular to a double-layer high-temperature superconducting magnetic levitation system for vehicles. Background technique [0002] High-temperature superconducting magnetic levitation technology, due to the unique magnetic flux pinning characteristics of high-temperature superconductors, has the advantage of self-sustaining and stable suspension, and has shown good application prospects in frictionless bearings, flywheel energy storage, rail transportation and other fields. Among them, the birth of the world's first manned high-temperature superconducting magnetic levitation test vehicle in my country in 2000 demonstrated the great attraction of high-temperature superconducting magnetic levitation technology in future new (high-speed, environmentally friendly, comfortable, etc.) rail vehicles, which aroused the international community's attention. ...
