摘　　要：磁浮列车的结构参数、磁场分布关系到磁体斥力、效率和可靠性,因此有必要对磁体的整体结构分布、磁极数、磁体厚度、气隙等参数及其构成的磁场进行深入研究。基于磁路设计的基本原理,本文采用MATLAB、ANSYS软件,探讨永磁悬浮电磁导向磁浮列车的磁场分布及其大小的影响因素,分别研究永磁场的二维平面分布和三维立体分布,通过磁场分析、建模,对其磁场进行数值计算。结果表明,采用本文数值仿真方法计算的气隙内磁感应强度及其磁力线分布,为最终确定磁浮列车的稳定悬浮间隙大小提供重要数据。The structural parameter and magnetic field situation of vehicle are related to the capability, efficiency and reliability of magnet levitation. It is necessary to study the whole magnet structural distribution, thickness, air-gap and numbers of magnet poles. Based on the basic principle of magnetic circuit design, the software MATLAB and ANSYS were used to research the two-dimension, three-dimension field distribution and its influencing factor of the vehicle levitated by permanent magnets and oriented by electromagnets. Magnetic field analysis and model building are used to carry out numerical calculation. Experimental results indicated that the magnetic induction intensity parameter obtained by the method supplies important data for defining the stable levitation gap.
