The magnetic suspension systems that they are basis of maglev trains divided in two classes: electrodynamic suspension (EDS) and electromagnetic suspension (EMS). EDS is based on repulsive forces acting on a magnet and is inherently stable system and even has well robustness in many cases with open loop control. But EMS is based on attractive forces acting on a magnet, is inherently unstable sy...

Abstract The effect of ground condition on unsteady aerodynamic performance a maglev train was numerically investigated with an IDDES (Improved Delayed Detached Eddy Simulation) method. accuracy the numerical method has been validated by wind tunnel experiments. flow structure, slipstream and force around under stationary moving conditions were compared. Track play leading role in influence wak...

Dynamic stability analysis of superconducting electro-dynamic maglev train under lateral and yawing motion condition is the key research content. The novel three-dimensional electromagnetic model integrated linear synchronous motor in with operation proposed, which can not only simultaneously achieve propulsion, levitation guidance performances vehicle, but also analyze dynamic performance cond...
