High-speed running maglev trains interacting with elastic transitional viaducts
Engineering Structures, 2019Abstract This paper presents a general framework for the dynamic analysis of high-speed maglev trains running on elastic transitional viaducts, a complicated problem that lacks an efficient analysis tool. Unlike the straight and circular tracks, both the curve radius (CR) and height difference (HD) between the outer and inner rails vary along the ...

The aerodynamic performance of moving high-speed maglev train–guideway system under crosswind
The Physics of FluidsWhen a high-speed maglev train runs on the guideway, its running stability can be easily disturbed by crosswinds. The guideway-holding configuration of the maglev train and the maglev train positioning will significantly affect the aerodynamic flow ...

Research on Absolute Positioning System for High-speed Maglev Train
2007 International Conference on Mechatronics and Automation, 2007In the high-speed Maglev system, accurate real time information of the train position is essential for stable, safe and efficient train operation. To detect the absolute location of the Maglev train, a detection scheme was proposed based on electromagnetic induction theory. In this scheme, the absolute position of the maglev train was detected by using

Design of magnetic levitation electromagnet for High Speed Maglev train
2013 International Conference on Electrical Machines and Systems (ICEMS), 2013This paper deals with the design of levitation electromagnet for super high speed magnetic levitation (Maglev) vehicle. Electromagnetic characteristics of levitation magnet are analyzed by finite element analysis. Levitation force ripples and cogging force are reduced by adopting core separation.
