【摘要】：高温超导磁悬浮列车,作为高温超导的一种典型应用,由于其独特的自稳定性以及高速、环保、节能、低噪等优势,得到了越来越广泛的关注和研究。本文基于真空管道高温超导磁悬浮回旋系统,主要针对一种新型的侧挂式高温超导磁悬浮高速回旋系统,以实验的方式,模拟系统运行时的一些情况,探索侧挂式运行模式下的悬浮力和导向力的特点和变化,寻求最佳的运行参数。本文还针对高温超导磁悬浮系统中使用的永磁轨道,研究了三种不同聚磁夹铁厚下,不同排布不同偏心的超导块的悬浮力,分析了其对于侧挂式悬浮系统运行稳定性的影响,为侧挂式悬浮系统的建立提供一定的依据。第一章主要介绍了本文的课题背景,国内外高温超导领域的一些研究进展,简述了高温超导磁悬浮领域一些应用。最后叙述了实验所用的仪器和超导块材。第二章简要介绍了磁悬浮技术的主要应用之一,磁悬浮列车,包含了常导磁悬浮和超导磁悬浮技术。对于高温超导磁悬浮,介绍了其悬浮原理和目前的一些实物模型。第三章主要讨论了侧挂式高温超导回旋系统,介绍了其结构特点和优势。针对侧挂式悬浮系统在运行时悬浮间隙剧烈减小和难以保证超导块材场冷之后在运行时处于轨道正中心这两个特点,设计并进行实验,测试了偏心情况下悬浮间隙的减小对悬浮力和导向力变化的影响,得出了以排布超导块方式改善悬浮系统稳定性的结论。第四章研究了三种不同厚度夹铁(4mm、6mm、8mm)的永磁轨道,对其空间磁场进行了仿真,并通过实验探索了夹铁厚度对于不同排布、不同偏离轨道距离的超导块悬浮力的影响。得出了对于侧挂式系统较为优化的夹铁厚度参数和排布方式选择。
[Abstract]:High temperature superconducting maglev train, as a typical application of high temperature superconductivity, because of its unique self-stability and high speed, environmental protection, energy saving, low noise and other advantages, Based on the high temperature superconducting magnetic levitation gyrotron system of vacuum pipeline, a new type of high temperature superconducting magnetic levitation high speed gyrotron system with side mounted superconducting magnetic levitation has been studied in this paper. In order to simulate the operation of the system, the characteristics and changes of the levitation force and the guiding force in the side-mounted mode are explored, and the optimum operating parameters are sought. The permanent magnet orbit used in the high-temperature superconducting maglev system is also discussed in this paper. In this paper, the levitation force of superconducting blocks with different eccentricity and three different thicknesses of polymagnetic clamps is studied, and its influence on the stability of side-mounted suspension system is analyzed. The first chapter mainly introduces the background of this paper and some research progress in the field of high temperature superconductivity at home and abroad. Some applications in the field of high temperature superconducting maglev are briefly described. Finally, the instruments and superconducting blocks used in the experiment are described. Chapter two briefly introduces one of the main applications of magnetic levitation technology, the maglev train, The levitation principle and some current physical models of HTS maglev are introduced. In Chapter 3, the side-mounted HTS gyrotron system is discussed. The structural characteristics and advantages of the system are introduced. Aiming at the two characteristics that the suspension gap of the side-mounted suspension system decreases sharply during operation and it is difficult to ensure that the superconducting bulk material field is in the center of the orbit after cold operation, the design and experiment are carried out. The influence of the decrease of suspension clearance on the variation of levitation force and guiding force under eccentric condition is tested, and the conclusion is drawn that the stability of suspension system can be improved by arranging superconducting blocks. In Chapter 4th, three kinds of permanent magnetic orbits with different thickness (4 mm ~ 6 mm ~ 8 mm) are studied. The space magnetic field is simulated, and the different arrangement of iron clip thickness is explored through experiments. The influence of the levitation force of the superconducting block with different deviating distance from the orbit is obtained. The optimum parameters of the thickness of the iron clip and the selection of the arrangement for the side-mounted system are obtained.
