The invention provides a high-temperature superconducting maglev train with a sandwich structure. Six suspension frame sub-systems are arranged at the bottom of each carriage; the cross section of a suspension frame is a rectangular frame with an opening in the bottom, rectangular liquid nitrogen low-temperature containers are installed on the two side frames of the opening in the bottom of the suspension frame and corresponding upper side frames on the two sides respectively, and cylindrical high-temperature superconductor combinations are installed in the rectangular liquid nitrogen low-temperature containers; air springs are arranged between the bottom of the carriage and the suspension frame; a rail system comprises a permanent magnet rail and a T-shaped beam; the permanent magnet railis double rails which are respectively positioned on two sides of the T-shaped beam, are clamped in the rectangular frame of the suspension frame, and are positioned between the upper and lower layers of high-temperature superconductor combinations; the T-shaped beam penetrates through the opening in the bottom of the suspension frame. The longitudinal space is fully utilized on the basis of saving the transverse space of the rail, and the sandwich-structure high-temperature superconducting maglev train not only increases the levitation force of the train, but also fully utilizes the magneticfields on the upper and lower surfaces of the permanent magnet rail.
Description
technical field [0001] The invention relates to the technical field of high-temperature superconducting maglev, in particular to a high-temperature superconducting maglev train with a sandwich structure. Background technique [0002] Due to the friction loss and speed limitation of traditional wheel-rail trains, it is necessary to develop non-contact maglev trains. Maglev trains are generally divided into electromagnetic levitation trains, electric levitation trains and high-temperature superconducting maglev trains according to their working principles. Due to the high active feedback control required by electromagnetic levitation and the high maintenance cost of the low-temperature superconducting low-temperature environment of electric levitation, the high-temperature superconducting maglev train is a magnetic levitation train based on the magnetic flux pinning between the high-temperature superconductor and the permanent magnet track. It can be stably suspended on the t...
