Abstract

The invention discloses an ultra-high-speed magnetic levitation test system adopting differential levitation guide and a bilateral linear motor. The ultra-high-speed magnetic levitation test system comprises a pneumatic streamline shell, a supporting walking mechanism, a differential levitation magnet, a differential guide magnet, a levitation rail surface, a guide rail surface, a linear motor rotor, a linear motor bilateral stator and a rail infrastructure. The supporting walking mechanism comprises an upper-layer vehicle body frame, a lower-layer L-shaped supporting arm and a rotor fixing base. A sleeper part of the track infrastructure extends into a suspension cavity defined by the lower-layer L-shaped supporting arm and the upper-layer vehicle body frame, the differential type suspension magnet is vertically arranged in the suspension cavity, and the differential type guide magnet is transversely arranged in the suspension cavity. Structural switching of an electromagnetic attraction force and electric repulsion force two-type suspension guide scheme and an asynchronous induction and permanent magnet synchronous two-type linear motor mover scheme is realized, and full technical verification and performance comparison can be performed on the two-type suspension guide and linear motor schemes. And a theoretical basis and a test support are provided for research and development of an ultrahigh-speed magnetic levitation system and selection of related technical schemes.

Description

Technical field

[0001] The invention belongs to the technical field of high-speed maglev and electromagnetic propulsion, and specifically relates to an ultra-high-speed maglev test system adopting a differential suspension guide and a bilateral linear motor.Background technique

[0002] According to the levitation mechanism, the magnetic levitation system is mainly divided into electromagnetic levitation type (EMS: Electromagnetic Suspension) and electric levitation type (EDS: Electrodynamic Suspension). The two use electromagnetic suction and electric repulsion to achieve levitation; if they are divided into four types according to the operating speed : Low speed (≀100km / h), medium speed (100~350km / h), high speed (350~600km / h) and super high speed (β‰₯600km / h). Compared with traditional contact mechanical supports such as wheel sets, sliders, bearings, etc., the magnetic levitation system adopts non-contact levitation support, which can effectively compensate for the inherent defects of me...
