摘要
通过不同条件下的悬浮力测量实验,研究冷却条件、场冷距离、轴距对单磁体式超导倒挂模型的引力特性的影响,在确定悬浮力的有限元仿真方法可行的基础上,仿真得到组合磁体式超导倒挂模型中不同磁极组合形式下的超导引力特性。实验和仿真结果表明:场冷的退磁过程能够获得较宽的超导引力区域,且场冷距离越小,轴距越小,组合磁体的磁极数越少,引力极大值越大。
Several experiments of levitation force measurement were made to study different parameters effects on the single magnetic inversion model of HTS under cooling condition,FC position and eccentric distance were changed.On the base of a practical finite element method for the levitation force simulation,magnetic attraction forces of modular inversion model of HTS were obtained under different modular formats.Experimental results and simulations show that FC condition can get a wider range of magnetic attraction force and a more large value can be acquired when FC position is lower,eccentric distance is smaller and the number of magnetic poles is less.
