摘　　要：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模型方程。在求解过程中采用磁通流动蠕动模型,通过伽辽金有限元离散,解出超导体电流密度分布,计算磁悬浮力并分析磁悬浮力磁滞性质。An equation was established in YBCO superconductor - NdFeB permanent magnet system based on flux flow and creep model. The electromagnetic derivative equation was transformed into linear equation. By Galerkin FEM, the distribution of shielding current and the levitation forces were solved. The hysteretic effect was anerlized.
