利用自制的实验设备,采用两种不同结构的永磁轨道,本文实验研究了由三块多籽晶YBCO超导块材组成的超导阵列的悬浮力和导向力随块材之间缝隙的变化关系,分析了块材之间的电磁相互作用对其悬浮力的影响。结果表明,块材之间的相互作用对其悬浮力的影响很弱,而块材之间间隙的改变对其悬浮力和导向力的影响却非常明显,具体表现为:对于正上方水平磁场分量占优的永磁轨道,增加块材之间的间隙会提高导向稳定性,但同时会降低悬浮能力;对于正上方竖直磁场分量占优的永磁轨道,增加块材之间的间隙会提高悬浮能力,但同时会降低导向稳定性。由此可见,对于一个给定的磁悬浮系统,可以简单地通过改变块材之间的间隙来满足不同应用条件下对悬浮能力和导向稳定性的需求。
Using self-made experimental equipment and two kinds of permanent magnet orbits with different structures, this paper experimentally studied the levitation force and the guiding force of the superconducting array composed of three multi-seed YBCO superconducting blocks with the change of the gap between the blocks Relationship between the block interaction between the impact of its levitation force. The results show that the interaction between the blocks has a weak influence on the levitation force, and the influence of the change of the gap between the blocks on the levitation force and the guiding force is very obvious. The specific performance is as follows: for the horizontal magnetic field component Dominating permanent magnet orbital, increasing the clearance between the blocks will improve the guiding stability, but at the same time it will reduce the levitation ability; for the permanent magnet track with the vertical magnetic field component directly above, increasing the gap between the blocks will increase Suspension capability, but at the same time will reduce the steering stability. Thus, for a given magnetic levitation system, the need for suspension capacity and guidance stability for different applications can be met simply by changing the gap between the blocks.
