Abstract

The invention provides a superconducting magnetic levitation damping system and a control method thereof, and relates to the technical field of superconducting magnetic levitation, the superconducting magnetic levitation damping system comprises a permanent magnet track, a levitation Dewar, a superconductor block and a shunt damping system, the superconductor block is arranged in the levitation Dewar, and in a temperature environment provided by the levitation Dewar, the superconductor block repels the permanent magnet track to provide suspension force for the train; and the shunt damping system is arranged in the suspension Dewar, the shunt damping system is arranged on the inner wall of the suspension Dewar, when a train runs, the shunt damping system generates an induced magnetic field which repels the magnetic field of the permanent magnet track, the vertical stabilizing assembly is arranged in the suspension Dewar, and through the electromagnetic induction phenomenon, and by means of the magnetic field gradient generated by the permanent magnet track in the vertical direction, vertical vibration of the train is reduced, the dynamic stability of the train is improved, and the comfort of the train using the embodiment is improved.

Description

technical field [0001] The invention relates to the technical field of superconducting maglev, in particular to a superconducting maglev damping system and a control method thereof. Background technique [0002] With the development of superconducting technology, the high-temperature superconducting magnetic levitation technology with the main characteristics of frictionless, low energy consumption and low pollution has great potential to become a new high-speed rail transportation mode. The suspension system is the core subsystem of the HTS maglev system, and its performance determines the performance of the vehicle. At present, regarding the improvement of dynamic characteristics: mainly for trains. But, mainly adopt damping component to connect between suspension frame and car body, as air spring, but its complicated structure is unfavorable for actual implementation. Contents of the invention [0003] The object of the present invention is to provide a superconductin...
