Description

technical field [0001] The invention belongs to the technical field of vehicle magnetic suspension or suspension, in particular to a superconducting magnetic suspension train test platform and a disturbance resistance method. Background technique [0002] The magnetic levitation train realizes the non-contact suspension and guidance between the train and the track through electromagnetic force. It not only runs fast, but also runs smoothly and comfortably. It has no noise and does not emit harmful waste gas, which is conducive to environmental protection. Superconducting materials are a powerful choice for generating the levitation force of maglev trains due to their unimpeded high current density. [0003] During the operation of the superconducting maglev train, the superconducting magnet may enter the quench state under the action of some sudden disturbance or intrinsic defect. In this state, in order to protect the train, the superconducting magnet needs to be released ...

AI Technical Summary

Problems solved by technology

On the other hand, superconducting magnets are expensive, and directly using superconducting magnets for testing will make the test system economically inefficient

And because the train protection action is immature, the protection failure may occur during the test process, causing great economic losses

[0004] Due to the special closed-loop operating conditions and quench propagation characteristics of superconducting materials, the control strategy for superconducting maglev trains is not yet clear. Therefore, it is necessary to build an efficient and economically feasible test platform to simulate trains in the formal process. Various disturbances, vibration resistance, and motion characteristics in the case of superconducting coil quenching, and then optimize the control strategy to ensure the smooth and safe operation of the car body
