Maglev train system and maglev track thereof

Abstract

The invention discloses a maglev train system and a levitation track thereof. The maglev train system comprises two tracks arranged in parallel, and is characterized in that a permanent magnet array and a superconducting driving module are embedded in the two tracks, and superconducting levitation coils for levitation and driving are arranged at the corresponding positions of the two sides of a superconducting levitation train; the permanent magnet array is formed by splicing a plurality of polygonal permanent magnets with different magnetizing directions, and the polygonal permanent magnets are polygonal combinations or single polygons which can be arranged in a plane rotating mode to fill the whole plane. According to the invention, the permanent magnets with different magnetizing directions are spliced to form a permanent magnet array, and through different topological structures such as triangles and rectangles, magnetic steel magnetizing in the horizontal direction and the vertical direction can be completed, and magnetizing at different angles with the horizontal direction can also be completed. By adjusting the magnetizing angle, the magnetizing direction of the permanent magnets regularly arranged on the cross section of the track can be closer to the direction of a magnetic field freely propagating in the air, so that the magnetic field enhancement with a better effectis realized.

Description

technical field [0001] The invention relates to the technical field of superconducting magnetic levitation, in particular to a magnetic levitation train system and a levitation track thereof. [0002] technical background [0003] The current general-purpose superconductor is the second type of superconductor. The Meissner effect in the mixed state is not complete. The thinner superconductor will form a quantized magnetic flux channel inside to allow the magnetic field lines to pass through. The passing magnetic field lines will pin the superconducting material. If the position is deviated, the magnetic field lines will pass through the magnetic flux pipeline with a longer path, and according to the first theorem, the superconducting material will return to its original state. position force. Therefore, the high-temperature superconducting suspension system of the second type of superconductor has the property of self-stabilization, and does not need an additional control sy...

Problems solved by technology

[0005] The permanent magnet rails in the traditional superconducting suspension model are only arranged in an N-S manner through permanent magnets to form a stable magnetic field to achieve the purpose of suspending superconducting materials. Rare-earth permanent magnets are selected, and even so, the surface magnetic field intensity provided by the orbits is very low, which has a very limited effect on enhancing the suspension force of superconductors
