Embodiment Construction

[0012] Such as figure 1 and figure 2 As shown, the present invention includes a vacuum pipeline 1, a linear motor 2, a maglev track 3, a maglev vehicle 4, and the like. The test line is to arrange the linear motor 2, the maglev track 3 and the maglev vehicle 4 inside the vacuum pipeline (1), realizing the combination of the superconducting maglev vehicle and the vacuum pipeline circuit.

[0013] In a specific embodiment, such as image 3 The maglev track 3 shown is set inside the vacuum pipeline 1. The track is a double-track parallel structure and is composed of a Halbach-type neodymium-iron-boron magnet array. The magnetic field provided by the track can make the high-temperature superconducting maglev vehicle run stably.

[0014] The linear motor 2 is responsible for driving / braking the maglev vehicle. It has the characteristics of low noise and high operation stability, and can realize non-contact operation control, which effectively improves the high-speed reliability ...

Abstract

The invention discloses a loop test track for a vacuum pipeline high-temperature superconducting magnetic levitation train. The loop test track is formed by a magnetic levitation system and a vacuum pipeline (1), wherein the magnetic levitation system is composed of a linear motor (2), a magnetic suspension track (3) and a magnetic levitation train. The magnetic levitation system is nested in the vacuum pipeline (1), so as to form an airtight negative pressure pipeline environment for realizing low resistance operation of the superconducting magnetic levitation train and the vacuum pipeline route. The loop test track disclosed by the invention integrates the superconducting magnetic train and the vacuum pipeline route, displays an advanced track traffic tool, and satisfies the demands of a loop test track for a manned high-temperature superconducting magnetic levitation train, a vacuum pipeline high-temperature superconducting magnetic levitation running test and dynamic characteristic study of high-temperature superconducting magnetic levitation system.

Description

Technical field: [0001] The invention relates to a superconducting maglev vehicle test device and a transportation test line system, in particular to a vacuum pipeline high-temperature superconducting maglev vehicle ring test line. Background technique: [0002] High-temperature superconducting maglev vehicle is a very promising model in maglev vehicles, and it is also very suitable for vacuum pipeline transportation systems. Therefore, the vacuum pipeline high-temperature superconducting maglev vehicle is expected to become a new advanced transportation system. The basic principle is: construct a pipeline on the ground or underground, lay the permanent magnetic track used by the high-temperature superconducting maglev vehicle in the pipeline, and pump it into a certain vacuum. Finally, the high-temperature superconducting maglev vehicle can run without mechanical contact and low air resistance in the vacuum pipeline, and its speed can exceed that of existing cars, trains an...
