In the study of high temperature superconducting maglev, the analysis of the forces acted on a high temperature superconductor (HTS) bulk is a basic issue, which can directly reflect the levitation and guidance performances of an HTS maglev system. In previous studies, the electromagnetic guideway was verified to be an alternative guideway type for HTS maglev. Recently, we carried out experimental and simulation work to investigate how a field cooled HTS bulk to interact with a reversed magnetic field. An E-type electromagnet is used to generate the required magnetic field. During the field reversing, forces acted on the HTS bulk were measured with a 3D force measuring system. In this paper, the forces on an HTS bulk in a reversed magnetic field are analyzed according to the experimental data and the results of finite element simulation. The magnetized status of a field cooled HTS bulk in a reversed magnetic field is discussed with a two region supposition. The influences of a reversed magnetic field on HTS maglev are summarized. These results may be of great significance not only for further study of HTS maglev, but also for some other applications, such as superconducting magnetic bearing and superconducting magnetic shielding.

反向磁场中 HTS 体的受力分析

在高温超导磁悬浮的研究中,作用在高温超导体(HTS)体上的力的分析是一个基本问题,它可以直接反映高温超导磁悬浮系统的悬浮和制导性能。在之前的研究中,电磁导轨被证实是 HTS 磁悬浮的替代导轨类型。最近,我们进行了实验和模拟工作,以研究场冷却 HTS 体如何与反向磁场相互作用。E型电磁铁用于产生所需的磁场。在场反转期间,作用在 HTS 体上的力是用 3D 力测量系统测量的。在本文中,根据实验数据和有限元模拟结果,分析了反向磁场中 HTS 体上的力。用两个区域假设讨论了在反向磁场中场冷却 HTS 体的磁化状态。总结了反向磁场对HTS磁悬浮的影响。这些结果不仅对高温超导磁悬浮的进一步研究具有重要意义,而且对于其他一些应用,如超导磁轴承和超导磁屏蔽具有重要意义。
