摘　　要：矢量磁位是电磁涡流场常用的分析方法.本文利用矢量电位法建立了NdFeB永磁铁和超导体相互作用的电磁场数学方程.对在求解过程中采用Kim模型,通过伽辽金有限元离散,形成线性方程组,解出超导体电流密度分布.这些分析结果为改进超导悬浮系统提供了理论依据.Current vector potential method is important in analysis of electromagnetic fields. An Equation was established in YBCO superconductor-NdFeB permanent magnet system based on Kim model. The electromagnetic derivative equation was transformed into linear equation by Galerkin FEM. The distribution of shielding current was solved. These results are potentiaiiy useful for the design of superconducting levitation system.
