摘要
超导磁悬浮具有自稳定性,广泛应用于超导磁悬浮轴承(SMB)、飞轮储能系统和磁悬浮列车等方面。鉴于超导轴承通常采用超导块材,故超导块材的特性直接影响轴承的性能。为此,本文对高温超导块材的悬浮力与悬浮刚度特性的影响因素进行深入梳理,如超导块材尺寸、磁场强度、磁场梯度和冷却方式等,在此基础上,进一步给出了超导磁悬浮轴承研究的国内外进展情况及发展建议。
Superconducting magnetic levitation offers stability and is widely applied in superconducting magnetic bearings(SMB),flywheel energy storage systems,and magnetic levitation trains.Currently,superconducting bearings typically use superconducting bulks,and the properties of these materials directly influence the performance of the bearings.This paper discussed the key factors influencing the magnetic levitation characteristics and levitation force of high-temperature superconducting bulks,such as the dimensions of the superconducting bulk,magnetic field strength,magnetic field gradient,and cooling method,as well as the current status of superconducting magnetic levitation bearing research both domestically and internationally,and provides development recommendations.
