Numerical Analysis of Crosswind Stability of Magnetically Levitated Trains

Using 2D,steady state,incompressible Navier Storkes equation and two equations k e turbulent model,the crosswind stability of magnetically levitated trains in different structures between guideway and vehicles have been calculated by finite volume method.The crosswind stabilities of the wheel rail trains and the magnetically levitated trains are compared.Results obtained show that the crosswind stability of the wheel rail vehicle is better than that of the magnetic levitated vehicle,and the crosswind stability of the EMS maglev vehicle is better than that of the EDS maglev vehicle.
