Abstract

The Electromagnetic Suspension (EMS) maglev is a promising solution for local transportation, characterized by its high-speed maglev technology and non-contact with the track. However, it faces challenges such as a limited suspension gap, high energy consumption, and heat dissipation issues. To address these concerns, this article proposes a novel hybrid electromagnetic support system (HESS) that combines high-temperature superconducting and normally conducting materials. By implementing HESS, not only can the suspension gap be increased but also the suspension capacity can be enhanced by 10 %. This paper begins by introducing the design scheme and working principle of HESS before analyzing how different parameter changes (e.g., stator current, excitation current, air gap) affect its electromagnetic performance.

高速磁悬浮列车高温超导混合电磁支撑系统设计及电磁特性分析

电磁悬浮（EMS）磁悬浮以其高速磁悬浮技术和与轨道不接触的特点，是一种很有前途的局部交通解决方案。然而，它面临着悬架间隙有限、能耗高、散热问题等挑战。为了解决这些问题，本文提出了一种新型的混合电磁支撑系统（HESS），该系统将高温超导材料与正常导体材料相结合。通过实施HESS，不仅可以增大悬架间隙，而且悬架能力可提高10%。本文首先介绍了HESS的设计方案和工作原理，然后分析了不同参数变化（定子电流、励磁电流、气隙）对其电磁性能的影响。

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.
