Modeling and Analysis of Suspension Frame of Maglev Train

Journal of Physics: Conference Series, 2020
Abstract Based on the acceleration feedback system, the vertical dynamic model of the low-speed maglev train is established. By decoupling the suspension frame module, the author conducted a stress analysis of the single-sided and the entire suspension system, and established a system dynamics model of the suspension frame.

IMPLEMENTATION MODEL OF MOTOR TRACTION FORCE OF MAGLEV TRAIN

Science and Transport Progress, 2016
Purpose. Traction force implementation (TFI) by the motor of magnetic levitation train (MLT) occurs in the process of electric-to-kinetic energy transformation at interaction of inductor and armature magnetic fields. Ac-cordingly, the aim of this study is to obtain a correct description of such energy transformation. Methodology.

Maglev trains

, 2014
Maglev trains are wonderful inventions that fly on air. They use magnets to levitate and propel the trains forward. There is no friction between the train and the track! The batteries can levitate the train for 30 minutes without any additional energy.

An Electromechanical Coupling Resonance Suppression Method for IPMSM Drive System Considering the Fluctuation of DC‐Link Voltage

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
With the consideration of the DC‐link voltage fluctuation, the motor output torque contains a large number of fluctuating components, which may trigger electromechanical coupling resonance (EMCR) and deteriorate the system control performance. In order to solve this problem, the model of the electromechanical coupled system is established, and the ...
