Maglev vehicle unilateral track coupling vibration test bed device

Abstract

The invention discloses a maglev vehicle unilateral track coupling vibration test bed device. The test bed device comprises a ground installation foundation platform, a suspension electromagnet bracket and an air spring arranged at the middle of the upper beam of the suspension electromagnet bracket. The test bed device also comprises a vibrating beam system, an electromagnetic exciting system, a suspension control system and a suspension quality simulation system, wherein the vibrating beam system comprises a vibrating beam and a stator; the stator is fixed in the middle position of the lower surface of the vibrating beam; the electromagnetic exciting system is connected with the end part of the vibrating beam; the suspension control system comprises a suspension controller, a suspension sensor and a suspension electromagnet; the suspension electromagnet is arranged on the lower beam of the suspension electromagnet bracket; and the suspension quality simulation system is connected with the suspension electromagnet bracket through a spring device. By adopting the test bed device, the suspension control-bridge dynamic irregularity-suspension frame coupling vibration laboratory simulation of the maglev vehicle can be realized.

Description

technical field [0001] The invention relates to a train vehicle-rail coupling vibration test bench device, in particular to a maglev train unilateral vehicle-rail coupling vibration test bench device. Background technique [0002] In the related research of maglev trains, suspension control and vehicle-rail coupled vibration are the two major difficulties, which are related to the stability and safety of maglev trains. Through the research on maglev trains, it is found that it is difficult to carry out special test research on the characteristics of track beams and the coupled vibration of trains and rails on the actual line, and it is best to carry out in the laboratory. A preferred approach in scientific research. In the research at home and abroad, for the suspension problem of maglev train, the simplified model is generally used for single-point suspension control research, or the whole vehicle is directly used for actual debugging. The former research is too simple an...

AI Technical Summary

Problems solved by technology

The former research is too simple, not targeted, and cannot reflect the complex "suspension control-bridge-suspension frame mechanical structure coupled vibration environment", while the latter is an experiment under a fait accompli and cannot achieve the effect of optimizing the track beam

Therefore, these two test methods are neither ideal nor reasonable, and there are relatively large deficiencies in test methods and test methods.
