Embodiment Construction
[0037] The present invention will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.
[0038] Considering that in the existing high-temperature superconducting maglev system, the permanent magnet track does not add a superelevation structure or adopts a geometric superelevation at the curve, the former is likely to cause the impact caused by the sudden change of the radius of curvature of the track, while the latter is easy to cause the impact caused by the splicing seam of the magnet. Geometric irregularities of the track occur at places, which causes a decrease in ride comfort. The invention provides a superhigh magnetic field structure suitable for high-temperature superconducting magnetic levitation permanent magnet tracks. This magnetic field superelevation structure can effectively and controllably complete the superelevation function without affecting the geometric smoothness of the track.

The invention relates to a high-temperature superconductivity magnetic suspension technique, in particular to a magnetic field extra-high structure of a high-temperature superconductivity magnetic suspension permanent magnet railway, which is used for substituting a conventional geometric extra-high structure and solving the problem that the railway is not smooth caused by splicing of magnets. The structure comprises a permanent magnet railway, magnetic conducting structures and a non-magnetic pedestal, wherein the permanent magnet railway adopts a structure of Halbach type permanent magnets, and the column number of the Halbach type permanent magnets is an odd number which is five or above; when an extra-high structure is needed, independent permanent magnet structures are additionally arranged under a lower layer, the column number of the independent permanent magnet structures corresponds to the column number of upper-layer vertical magnetisation magnets, and the independent permanent magnet structures are mounted under the upper-layer vertical magnetisation magnets and are used for enabling the magnetic field to be inclined so as to realize the extra-high structure; the magnetic conducting structures are mounted on two sides of an extra-high section permanent magnet railway, and the magnetic field of the railway is optimized; the non-magnetic pedestal is used for fixing the permanent magnet railway and the magnetic conducting structures. When trains pass through curve railways, the magnetic field extra-high structure designed by the invention can enable train bodies to generate incline to a certain extent, weight components provide centripetal force, the horizontal incline of the train bodies is reduced, and the comfort degree is improved.
Description
technical field [0001] The invention relates to a high-temperature superconducting magnetic levitation technology, in particular to an ultra-high magnetic field structure of a high-temperature superconducting magnetic levitation permanent magnet track. Background technique [0002] The existing high-temperature superconducting maglev short-distance test lines have been established in China, Brazil, Germany and other countries. The characteristics of the track lines in each country are different, but there are curves in all of them, and they have not yet adopted super-high design. The height of the inner and outer rails of the track is the same at the bend, and the track is not inclined. [0003] When passing through a curve at a fast speed, due to the centrifugal effect, the car body will be subjected to a large lateral acceleration, and the vehicle will deviate to the outside of the track, which will affect the comfort of passengers and the stability of the train operation;...
