摘要: |
高温超导磁悬浮装置, 如磁悬浮列车和磁悬浮轴承在高速运行时, 空间磁场交变及不均匀性扰动会引发超导块材内部损耗并影响性能, 传统均匀时变磁场实验研究及仿真模拟无法满足实际工程应用情况. 本文通过设计不同永磁阵列得到不同波形, 在高速系统驱动下得到不同交变频率下超导块材损耗特性, 发现全波型损耗较半波型损耗高, 并研究了不同磁场构型悬浮力衰减特性, 可为高速超导磁浮应用提供实验依据. |

Abstract: |
High temperature superconducting magnetic levitation devices, such as magnetic levitation trains and magnetic levitation bearings, can cause internal loss and affect the performance of superconducting blocks due to the alternation of space magnetic field and non-uniform disturbance. Traditional uniform time-varying magnetic field experimental research and simulation can not meet the actual engineering application. In this paper, different waveforms are obtained by designing different permanent magnet arrays, and the loss characteristics of superconducting bulk materials at different alternating frequencies are obtained under the drive of high-speed system. It is found that the full-wave loss is higher than the half-wave loss. The levitation force attenuation characteristics of different magnetic field configurations are studied, which can provide experimental basis for the application of high-speed superconducting magnetic levitation. |
