Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2018 The rated suspension gap of a low-to-medium-speed maglev train with electromagnetic suspension is normally 8–10 mm. However, while either passing over a bridge or being stationary on one, the maglev train deforms the bridge and therefore alters the ...

Study on the settlement caused by the Maglev train
Natural Hazards, 2014Because of the high speed, the operation safety of Maglev train is heavily affected by the differential settlement. As the first commercial service, the operation of Maglev train has been for a few years in Shanghai, which provides us a chance to investigate the settlement along the magnetic suspension line and the subsidence induced by Maglev train ...

PID Control to Maglev Train System
2009 International Conference on Industrial and Information Systems, 2009The advantage of linear PID control is easy tuning, but its obvious disadvantage is the conflict between the stiffness and the performance when this approach is applied to magnetic suspension system. In order to enhance the stiffness of the system, the usual way of linear PID control is to increase the proportion feedback, but this approach is ...

Magnetic levitation (Maglev) is a technology where magnetic forces lift, propel, and guide a vehicle over a guideway. This configuration eliminates contact between vehicle and guideway and permits speeds of up to 300 mph. The Federal Railroad Administration is evaluating the feasibility of Maglev construction in seven cities.

UAQ4 Levitating Train: Italian Maglev Transportation System
IEEE Vehicular Technology Magazine, 2014This article illustrates the University of L'Aquila model 4 (UAQ4) Italian maglev train, a transportation system with zero motion resistance (except aerodynamic drag) and greatly reduced energy consumption, approaching zero at a low constant speed. The project is the result of more than 40 years of research in the field of nonconventional highspeed ...

Riding on air in Virginia [Maglev train]
IEEE Spectrum, 2002The first operational magnetic levitation system in the United States will carry students across a university campus. Other magnetically levitated trains may cover many more kilometers and run at much higher speeds, but riders of the one at Old Dominion University (Norfolk, Va.) will have someplace to go at the other end. Instead of being used for test

Optimisation Of The On-board Linear Generator In EMS-MAGLEV Trains
1997 IEEE International Magnetics Conference (INTERMAG'97), 1997The paper presents a fully automated procedure to optimize the performance of the on-board generator used in electromagnetic Maglev trains. The procedure utilizes FEM analyses to determine the mathematical model of the generator and then calculates the generator output characteristics by means of step-by-step numerical simulations.
