摘　　要：为了实现列车模型在永磁斥力和电磁吸力共同作用下的动态稳定悬浮,提出了一种永磁悬浮电磁导向列车模型．研究了其机械结构组成及其工作原理,建立了相应的数学模型,分析了各永磁铁组合斥力之间在空间三自由度方向的相互作用机理和基本特性,研究了列车模型的力平衡特性、自适应性及稳定性,提出了列车模型截面三自由度平衡控制问题的解决方案．研究结果表明,基于对称机械结构并经合理组合分布的永磁铁能实现列车模型悬浮．In order to achieve the objective of the dynamic steady suspension of a train model under the condition of excluding force both from permanent magnet and electromagnetism, the authors put forward a train model suspended by permanent magnet and oriented by electromagnetism. Based on the model the authors studied the mechanism and working principles, established its mathematics model, analysed the basic characteristics and the mechanics equilibrium in three directions and studied the characteristics of mechanics equilibrium, self-adjusting and stabilization. The authors also provided the solution about the equilibrium control problem in three directions. The article concluded that the train model can be floated under the condition of reasonable compounding of the permanent magnets and the electromagnetism.
