摘要根据一种计算超导体薄间隙磁场的方法, 设计了一种新型的超导磁悬浮支承结构。首先分析了其支承系统在无源悬浮条件下的力学特性式, 然后针对无源磁悬浮支承刚度低的缺点, 引入了线性反馈控制系统, 并分析了线性反馈控制下的力学特性。最后悬浮力的计算结果经过有限元计算验证, 一致性较好。本超导磁悬浮系统具有结构简单、电磁力计算方便等优点, 对设计超导加速度计和超导陀螺仪有重要的借鉴意义。

Abstract：Based on a method used to calculated the magnetic field in a thin clearance between superconducting blocks, in this paper, a new type of superconducting suspension system is designed. Force characteristics of the passive suspension system are firstly analyzed. Then aiming to improve the low supporting stiffness of the passive suspension system, a linear feedback control system is introduced and its force characteristics are also analyzed. Comparison between analytical results and finite element analysis (FEA) results shows a good agreement. With the virtue of simple structure and convenience of calculation of magnetic field, this suspension system has reference meaning to superconducting accelerometer and superconducting gyroscope.

Key words： Thin clearance magnetic field superconducting magnetic suspension shaping block superconducting accelerometer
