- 摘要:
- 针对一种微小卫星使用的超导磁悬浮储能及姿控飞轮结构,采用H方法(以磁场强度H作为独立变量)对飞轮的永磁结构转子与超导结构定子进行了耦合磁场分布和悬浮力的仿真分析。通过对比3种尺寸相同但构型不同的永磁结构,确定采用悬浮力最大且敏感元件区域磁场强度最小的Halbach构型作为飞轮转子的永磁结构。通过调整Halbach构型的中心磁体宽度和高度,并保持永磁结构的总体尺寸不变,以悬浮力最大为优化目标,兼顾敏感元件区域的磁场强度,获得了结构最优的Halbach构型永磁结构,计算悬浮力大小约1 084 N。
- Abstract:
- According to the requirement of micro satellite, a type of structure of HTS maglev energy storage and attitude control flywheel was proposed.Based the H-method, the magnetic field and levitation force of permanent magnetic(PM)structure coupled with HTS stator were analyzed through simulation calculation.Comparing three types of permanent magnetic structure, the Halbach configuration was adopted for its largest levitation force and lowest magnetic field in the sensitive component zone.By adjusting height and width of central magnet in Halbach configuration and keeping the size of the PM zone, aiming at largest levitation force and limiting external magnetic field, the optimal PM structure with levitation force about 1 084 N was obtained.
