Abstract: |
A structure scheme of high-speed maglev, which producing levitation, guidance and propulsion forces based on the high temperature superconducting ( HTS) flux-pinning effect and HTS linear synchronous motor respectively, was proposedto make the train can be levitating at the speed of 0, running at the speed of 500 km/h and without the special controlling system for levitation and guidance. The operation condition of a maglev train composing of 5 carriages was considered to design the HTS-permanent structure for levitation and guidance and the HTS linear synchronous motor for propulsion. The feasibilities of the HTS-permanent structure and HTS linear motor were verified based on finite element method models, respectively. The obtained results show that the proposed maglev based on HTS-permanent structure and HTS linear motor is the typical represent of advanced type of railtransit with the merits of levitating at speed of 0, running at 500 km/h and without the special control system for levitation and guidance. |
