摘　　要：超导块材和永磁铁相互作用形成悬浮系统。讨论了对超导块材进行网格划分的方法,利用矢量电位法建立了Nd-FeB永磁铁和超导体相互作用的电磁场数学方程。利用伽辽金法形成有限元线性方程组。求解过程中采用Kim模型作为迭代条件,解出超导体电流密度分布,并进行受力分析。A levitation system is composed of superconductor and permanent magnet. This paper describes how to divide the mesh of superconductor. The current vector potential method is adopted to establish the physical equations in NdFeB permanent magnetic - supercon- ductor system. These equations were converted into linear equations group with Galerkin method. In solving equations process, Kim model was as iterative conditions. The distribution of current density and levitation force can be solved.
