本文研究了YBCO高温超导磁悬浮系统在竖直方向上不同的悬浮高度,不同的振动频率扰动下的振动属性.研究表明在一般的小的扰动下,悬浮系统类似于一个弹簧系统,该系统可以恢复到初始的悬浮高度.而当系统受到一个共振频率的扰动时,系统会发生剧烈的振动,会引起能量的损失,悬浮高度的降低.系统的共振频率会随着系统初始悬浮高度的降低而增加.这些关系在改善一些磁悬浮系统的悬浮性能有着重要的意义.
The vertical vibration responses of YBCO superconductor maglev system on different suspension heights and different vibration frequencies are investigated in this letter. For lower vibration frequency, the system can resume the suspension height, like a spring system. The resonant frequency, which led to a small damping and an intense vibration, linearly increases when decreasing the gap between the superconductors and the magnet . It makes the energy loss and suspension height of the system significantly to be reduced. These relationships are useful in improving the levitation performance of high temperature superconductor maglev systems.
