| 摘 要： | 本文研究了YBCO块材排布方式与其在永磁导轨上悬浮力的关系.实验结果表明:悬浮力与随悬浮间距成指数关系.而YBCO块材在导轨上方排列方式的不同,导致沿轨道横截面方向,每块超导块获得的悬浮力平均值差异较大.当超导块集中分布于轨道上方磁场强度最大的区域时,超导块平均悬浮力最大.这意味着,与其他排布方式相比,在获得同等悬浮力情况下,这种排布方法的超导块用量最少.这一结果对于超导磁悬浮系统的设计具有指导意义。

| Abstract: | Relationship between levitation force of YBCO bulks and their arrangements over permanent magnet guideway was studied.The results show the exponential correlations between levitation force and suspension spacing.Otherwise,different arrangement of YBCO bulks over guideway results significantly different average levitation force of YBCO bulks assembled in cross section of magnet guideway.When all the YBCO bulks are arranged near the region with strongest magnetic field above guideway,the average of levitation... |
