摘　　要：为了分析中低速磁浮列车的悬浮性能,文章将两组刚性连接的电磁铁模块视为一个整体模块建立动力学方程,以质心坐标描述单模块电磁铁的运动状态,并通过三维有限元分析和线性插值获得任意电流和悬浮间隙下的悬浮力,基于该动力学方程和三维有限元分析值建立电磁铁静态悬浮特性仿真模型;与传统的单点悬浮控制模型相比,文章所建模型更符合中低速磁浮列车悬浮电磁铁的实际工作情况,为后续悬浮控制系统的设计和控制参数的计算奠定了一定的基础。In order to analyzes the levitation characteristic of middle and low speed maglev train,the dynamics equations are deduced by taking the two electromagnets connected directly as a whole unit. The motion state of the single electromagnet unit is described by the coordinate of center of mass, and the levitation forces under certain values of current and levitation clearance are obtained through 3D finite element analysis and linear interpolation. Subsequently,a kind of static simulation model for levitation characteristic of electromagnet is established, basing on the dynamics equations and 3D finite element analysis values. Compared with the traditional control model for single point levitation,the model established here is more in line with the actual situation of the electromagnet unit, and the foundation for design of levitation control system and calculation of control parameters could be laid.
