| 摘 要： | 利用二维定常不可压缩Navier-Stokes方程、K-E两方程紊流模型，采用有限体积法分析计算了不同车轨结构的磁浮列车横风稳定性，并与轮轨型列车的横风稳定性作了比较。数值分析结果表明，在横向风的作用下，轮轨型列车的横向稳定性优于磁浮列车，而吸力型磁浮列车的横向稳定性又优于U型线路斥力型磁浮列车。 |

| Abstract: | Using 2D,steady state,incompressible Navier-Storkes equation and two equations k-ε 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 vehic le is better than that of the EDS maglev vehicle. |
