摘要:
本文提出了一种高温超导磁悬浮轴承数值仿真方法,并对其悬浮力计算结果进行了验证。该方法采用基于磁场强度的H法对高温超导进行建模,利用间接耦合方法体现磁场对于超导作用,从而对高温超导磁悬浮进行仿真。该模型在有限元软件COMSOL Multiphysics中进行计算。此外,本文探讨了剖分网格对于模型计算时间、精度的影响和不同涂层导体堆叠方式对悬浮力的影响,以指导在实际应用中对于堆叠方式的选取。

Abstract:
This paper introduced a numerical model to study the performance of high-temperature superconductor magnetic bearing.The model was validated by the good agreement between the results of simulation and experiments in terms of levitation force.In this model the performance of high-temperature superconductor is expressed with H- formulation and the interaction between high-temperature superconductor and magnet is established by indirectly coupling.In addition,the influence of stack arrangement on the levitation force and the influence of meshon computing time and accuracy are also discussed in the paper.
Key words:  H-formulation  High-temperature superconductor magnetic levitation  Finite element method
