Abstract

As an important part of the high-temperature superconducting (HTS) maglev system, the performance and stability of the permanent magnet guideway (PMG) is directly related to the loading capacity and safe operation of the HTS maglev train. Therefore, it is necessary to carry out optimization research on the performance of PMG. At present, PMG optimization studies are mostly from the perspective of magnetic circuit, and seldom considered from the perspective of statistical analysis. In this paper, a PMG optimization method based on sensitivity analysis is discussed. First, the PMG dataset is established by simulation with parametric sweeping method. Then, the influence of permanent magnet (PM) dimension and grade on the electromagnetic force of HTS maglev system is investigated using sensitivity analysis method. And the optimization suggestions for the HTS maglev system are given. Finally, the optimization method is applied to present a PMG optimization case, and the optimization results show that the maximum vertical magnetic field is increased by 16.57 %, the maximum lateral magnetic field is increased by 10.97 %, the levitation force of the HTS bulks is increased by 3.23 %, and the guidance force is increased by 11.78 %.

基于灵敏度分析的HTS磁悬浮系统哈尔巴赫永磁导轨优化

永磁导轨作为高温超导（HTS）磁悬浮系统的重要组成部分，其性能和稳定性直接关系到高温超导磁悬浮列车的承载能力和安全运行。因此，有必要对永磁减速器的性能进行优化研究。目前PMG优化研究多从磁路角度出发，很少从统计分析的角度考虑。讨论了一种基于灵敏度分析的PMG优化方法。首先，采用参数扫描方法对PMG数据集进行仿真建立。然后，采用灵敏度分析方法研究了永磁尺寸和牌号对高温超导磁悬浮系统电磁力的影响。并对高温超导磁悬浮系统提出了优化建议。最后，将该优化方法应用于PMG优化实例，优化结果表明，最大垂直磁场增大16.57%，最大横向磁场增大10.97%，HTS体的悬浮力增大3.23%，引导力增大11.78%。

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
