本文利用排布在液氮低温容器底部的多块超导块以测试其悬浮特性.结果表明:YBCO块材在永磁导轨上的悬浮力与二者间距的变化过程有关;不同的变化过程会在相同的悬浮间隙位置得到不同的悬浮力.这一研究结果对磁悬浮列车的优化设计有着重要的意义.
High temperature superconductors (YBCO) Bulks were arranged on the bottom of a liquid nitrogen vessel to study the levitation characteristics.Results show that the levitation force of bulks is affected by process of variation of suspend gap.Different processes of variation of suspend gap may results different levitation force at the same suspend gap.This is meaningful for the design of high temperature superconducting maglev system.
