摘要:

從1911年發(fā)現(xiàn)超導現(xiàn)象至今，新型超導材料不斷涌現(xiàn)。隨著臨界溫度及內部磁通釘扎性能的不斷提升，實用型超導磁懸浮技術成為可能。本文首先介紹了當前主要的磁懸浮交通模式及其特點，具體包括常導電磁懸浮(EMS, electromagnetic suspension)、低溫超導電動磁懸浮(LTS EDS, low-temperature superconducting electrodynamic suspension)、及高溫超導磁懸浮(HTS Maglev, high-temperature superconducting magnetic levitation)。其次，針對高溫超導磁懸浮，重點闡述了其自穩(wěn)定懸浮原理、發(fā)展歷程以及相關實驗樣車研究現(xiàn)狀。2014年6月西南交通大學將高溫超導磁懸浮與真空管道相結合，成功搭建了新一代的真空管道高溫超導磁懸浮車試驗平臺“Super-Maglev”，以期探討高溫超導磁懸浮未來可能的交通模式與技術定位等問題。最后，本文總結了高溫超導磁懸浮相比于其他磁懸浮模式的優(yōu)勢，并進一步討論了可能的軌道交通應用速度等級。

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.
