Abstract

The invention discloses a method for testing suspension performance of a magnetic suspension system under different speeds. The method comprises the following steps: 1) establishing an electromagneticrailway, wherein the electromagnetic railway comprises ferromagnetic blocks and a plurality of first electromagnetic coils arranged at the two sides of each ferromagnetic block respectively, and setting mutually-independent second electromagnetic coils on the first electromagnetic coils respectively; 2) keeping a train body to stay suspended and unmoved, then, setting conduction time between theadjacent second electromagnetic coils and enabling K1-KN to be conducted in sequence; 3) obtaining simulated running speed of the magnetically-levitated train through a formula V=2f*L, wherein f is the reciprocal value of the conduction time; and 4) after setting the conduction time, controlling electric quantity input to the K1-KN through a controller, and adjusting the magnitude of a generated magnetic field to measure the suspension performance of the magnetically-levitated train under different speeds. The method can detect the suspension performance of the magnetically-levitated train under different speeds.

Description

technical field [0001] The invention belongs to the technical field of magnetic levitation, and in particular relates to a method for testing the levitation performance of a magnetic levitation system at different speeds. Background technique [0002] When measuring the running speed of the maglev system, the traditional method is to first build a permanent magnetic track, and then drive the car body forward or backward along the permanent magnetic track to test the superconducting block inside the car body. The change of the electromagnetic coupling relationship between the magnetic guide rails and the running speed of the car body. However, after the permanent magnet track is used for a long time, the magnetic field will be uneven, and the cost of building the permanent magnet track is high. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a method for testing the levitation performance of the ...
