高温超导磁悬浮轴承研发现状

摘要

As one of the most representative applications of self-stable high temperature superconducting magnetic levitation technology, high temperature superconducting magnetic bearing (SMB) can realize passive high-speed rotation without any friction, which provides a new way to markedly improve and upgrade the performance of present machinery and equipment with common bearings. In order to summarize the research and development status of SMB, the typical prototypes are described respectively from America, Germany, Japan and Korea, as well as other domestic and foreign groups. The key technical issues and present hotspot are pointed out and discussed to explain the future development and potential prospect.%高温超导磁悬浮轴承作为具有自稳定优势的高温超导磁悬浮技术最具代表性的应用之一,可实现无源的高速无摩擦旋转运行,为大幅度提高现有机器设备的性能及升级换代提供了新的途径.本文综述了近年来美国、德国、日本和韩国等国内外小组开展的高温超导磁悬浮轴承代表性样机研发现状,探讨了该项技术的关键难点问题,指出了当前研究的热点,阐述了可能的应用前景.
