【摘要】：高溫超導磁懸浮列車,作為高溫超導的一種典型應用,由于其獨特的自穩(wěn)定性以及高速、環(huán)保、節(jié)能、低噪等優(yōu)勢,得到了越來越廣泛的關注和研究。本文基于真空管道高溫超導磁懸浮回旋系統(tǒng),主要針對一種新型的側掛式高溫超導磁懸浮高速回旋系統(tǒng),以實驗的方式,模擬系統(tǒng)運行時的一些情況,探索側掛式運行模式下的懸浮力和導向力的特點和變化,尋求最佳的運行參數。本文還針對高溫超導磁懸浮系統(tǒng)中使用的永磁軌道,研究了三種不同聚磁夾鐵厚下,不同排布不同偏心的超導塊的懸浮力,分析了其對于側掛式懸浮系統(tǒng)運行穩(wěn)定性的影響,為側掛式懸浮系統(tǒng)的建立提供一定的依據。第一章主要介紹了本文的課題背景,國內外高溫超導領域的一些研究進展,簡述了高溫超導磁懸浮領域一些應用。最后敘述了實驗所用的儀器和超導塊材。第二章簡要介紹了磁懸浮技術的主要應用之一,磁懸浮列車,包含了常導磁懸浮和超導磁懸浮技術。對于高溫超導磁懸浮,介紹了其懸浮原理和目前的一些實物模型。第三章主要討論了側掛式高溫超導回旋系統(tǒng),介紹了其結構特點和優(yōu)勢。針對側掛式懸浮系統(tǒng)在運行時懸浮間隙劇烈減小和難以保證超導塊材場冷之后在運行時處于軌道正中心這兩個特點,設計并進行實驗,測試了偏心情況下懸浮間隙的減小對懸浮力和導向力變化的影響,得出了以排布超導塊方式改善懸浮系統(tǒng)穩(wěn)定性的結論。第四章研究了三種不同厚度夾鐵(4mm、6mm、8mm)的永磁軌道,對其空間磁場進行了仿真,并通過實驗探索了夾鐵厚度對于不同排布、不同偏離軌道距離的超導塊懸浮力的影響。得出了對于側掛式系統(tǒng)較為優(yōu)化的夾鐵厚度參數和排布方式選擇。
[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.
