The invention relates to the technical field of single levitation chassis testing for a maglev train, in particular to an electromechanical coupling vibration test device for the maglev train. The device comprises a primary platform for simulating ground support, a secondary platform which is positioned above the primary platform and simulates a track beam, and a track beam rigidity adjusting system for connecting the primary platform and the secondary platform, wherein the track beam rigidity adjusting system and the secondary platform supported by the track beam rigidity adjusting system form simulated maglev train track beam characteristics; and a hydraulic shock excitation system which applies excitation to the primary platform so as to simulate geometrical irregularity of track ground is fixed under the primary platform.

Description

technical field [0001] The invention relates to the technical field of maglev train single-suspension frame testing, in particular to an electromechanical coupling vibration test device for maglev trains, which can simulate the suspension control-track beam-suspension frame machinery of high-speed and low-speed maglev trains and single-suspension frame of maglev trains with different gauges Structurally Coupled Vibration Environments. Background technique [0002] The suspension control system of the maglev train is a key technology. Due to the interaction force between the suspension control and the elastic track beam and the vehicle mechanical structure, the mechanical properties of the track beam and the suspension frame structure have a great influence on the suspension control effect of the maglev train. There is a significant impact. At present, there is no test device capable of simulating the "suspension control-elastic bridge-suspension frame mechanism coupling vib...

AI Technical Summary

Problems solved by technology

At present, there is no test device capable of simulating the "suspension control-elastic bridge-suspension frame mechanism coupling vibration environment" at home and abroad. Therefore, in the actual application and development of maglev trains, the suspension stability of maglev trains is often encountered. Problem, in order to alleviate this problem as much as possible, the track beams are often made very large in the project, resulting in a substantial increase in construction costs, which is not conducive to the promotion of the use of maglev trains

At present, the levitation test of the maglev train either adopts a simplified model for single-point levitation control research, or uses the actual debugging research of the whole vehicle. frame mechanism coupling vibration environment", the latter is an experiment under the fait accompli and cannot achieve the best results

Therefore, these two test methods are neither ideal nor reasonable.
