磁浮列车直线电机建模分析

Analysis on ModeI Building of Linear Induction Motors for Magnetic Levitation Trains

以直线电机独具的“边缘效应”物理特征为中心，分别阐述了不计“边缘效应”、单独考虑横纵向二类“边缘效应”的建模方法，其中引入了“面电密”、“体电密”、“矢量磁位”等概念，使之分析简化、思路更清晰。

Centers on LIM“end一effect”physical characters,discusses the model building methodswhich ignore“end一ect”or only consider horizontal or vertical“end一effect”,in which some con-cepts such as“current density”and“magnetic vector potential”are introduced,so the thinking isvery simple and clear.
