| 摘 要： | 研究了磁铁厚度和YBCO超导体厚度对悬浮力的大小及系统动态特性的影响,通过分析得出磁悬浮系统中磁体和超导体厚度的最优值。通过悬浮力测试系统测得超导块尺寸为φ30mm×18mm时四块不同厚度的磁体的悬浮力以及磁体尺寸为φ30mm×10mm时六块不同厚度的YBCO超导体的悬浮力的大小;并在振动实验台上测试了上述情况下的振动特性。对动态曲线进行频谱分析,最终得出最优组合,从而对磁悬浮系统的磁体和超导体厚度进行了优化。

| Abstract: | The effect of thickness of magnets and YBCO superconductor bulks on suspended force was studied in this paper.Levitation forces of superconductor bulks with different thickness above magnets of φ30mm×18mm and φ30mm×10mm were examined,respectively.The optimal values of the thickness of the magnet and superconductor bulks were thus obtained.Furthermore,vibration responses of the levitation systems mentioned above were also studied,and the best combination of magnet and superconductor bulk was obtained according to spectrum analysis. |
