摘要:

從1911年發(fā)現(xiàn)超導(dǎo)現(xiàn)象至今，新型超導(dǎo)材料不斷涌現(xiàn)。隨著臨界溫度及內(nèi)部磁通釘扎性能的不斷提升，實(shí)用型超導(dǎo)磁懸浮技術(shù)成為可能。本文首先介紹了當(dāng)前主要的磁懸浮交通模式及其特點(diǎn)，具體包括常導(dǎo)電磁懸浮(EMS, electromagnetic suspension)、低溫超導(dǎo)電動(dòng)磁懸浮(LTS EDS, low-temperature superconducting electrodynamic suspension)、及高溫超導(dǎo)磁懸浮(HTS Maglev, high-temperature superconducting magnetic levitation)。其次，針對(duì)高溫超導(dǎo)磁懸浮，重點(diǎn)闡述了其自穩(wěn)定懸浮原理、發(fā)展歷程以及相關(guān)實(shí)驗(yàn)樣車研究現(xiàn)狀。2014年6月西南交通大學(xué)將高溫超導(dǎo)磁懸浮與真空管道相結(jié)合，成功搭建了新一代的真空管道高溫超導(dǎo)磁懸浮車試驗(yàn)平臺(tái)“Super-Maglev”，以期探討高溫超導(dǎo)磁懸浮未來可能的交通模式與技術(shù)定位等問題。最后，本文總結(jié)了高溫超導(dǎo)磁懸浮相比于其他磁懸浮模式的優(yōu)勢(shì)，并進(jìn)一步討論了可能的軌道交通應(yīng)用速度等級(jí)。

Abstract:

New superconductor materials have been constantly found since the discovery of superconductivity in 1911. With the critical temperature and the inherent flux-pinning property improved continually, the practical superconducting magnetic levitation (maglev) technology became possible. Firstly, the main maglev transportation methods and their characteristics are introduced. They are electromagnetic suspension (EMS), low-temperature superconducting electrodynamic suspension (LTS EDS), and high-temperature superconducting Maglev (HTS Maglev). Secondly, the development history and the state of the art of HTS Maglev around the word are emphasized and described in detail by focusing on its self-stable levitation characteristics. In June 2014, Southwest Jiaotong University built a test platform for HTS Maglev–evacuated tube transport (HTS Maglev–ETT), “Super-Maglev”. Based on the “Super-Maglev”, the HTS Maglev and the ETT concepts had been successfully combined. Finally, the prominent advantages of the HTS Maglev are summarized compared with other Maglev technologies. Furthermore, several potential rail transit applications with different speeds are proposed and discussed in order to gain accesses to the markets.
