Based on the foundation of the virtual prototype model of the medium-speed maglev train, using the mechanical dynamics and kinematics analysis software ADAMS, this paper expatiates on the following things. Firstly, it analyses the decouple of single magnetic bogie by the simulation and experimentation; secondly, adds the magnetic levitation control system to the single magnetic bogie model and simulates; thirdly, by simulating the motion of the train running on the different type of guideway, analyses the state of the train on the ramp and crankle;in the end ,this paper does a further research on how the magnetic levitation control system and guideway parameters affect the suspending gap when the train runs on the ramp and crankle .

论文在建立了中低速磁浮列车虚拟样机模型的基础上，借助于机械系统运动学及动力学分析软件ADAMS，首先从单转向架出发，仿真分析了磁浮列车单转向架的解耦能力；接着对单转向架样机模型进行了控制系统的仿真；然后对一辆整车在竖曲线和平曲线的运行在ADAMS中进行了仿真，分析了列车在坡道和弯道上的运行状态；最后对磁浮列车在坡道和弯道上运行时的系统性能进行仿真分析，进一步研究了控制系统和线路参数对磁浮列车悬浮性能的影响。
