Research and Experiment on the Vehicle and Guideway Coupling Relationship of High-speed Maglev Train in the Curve Negotiation

Abstract

When the high-speed maglev train is moving, with the increase of the vehicle speed, vehicle and guideway coupling vibration becoming a great impact on the safety and comfort. Since there is only Shanghai magnetic suspension demonstration operation line in commercially operation in the world at present, the research on the vehicle and guideway coupling of high speed maglev system, especially in the curve negotiation is insufficient. Based on the vehicle acceleration data of the elastic suspension frame and the guideway which is acquired from the Shanghai high-speed maglev test line, through analyzing the behavior and structure performance of train body and the guideway during moving, the research provides experimental basis for further work on the vehicle and guideway coupling relationship of high speed maglev train in the curve negotiation.
