Abstract

Superconducting electrodynamic suspension (SCEDS) possesses superiority over others in self-stability, technology maturity, and great levitation gap, rendering it the optimal alternative for sub-sonic travelling integrated with the evacuated tube. However, the coupling relationship among tube and SCEDS train remains ambiguous. As a solution, this work investigates their electromagnetic couplings through demonstrative full-scale simulation model. Initially, the integrated structure and principles are introduced. Subsequently, a simulation model encompassing the tube, superconducting magnets, levitation coils and propulsion windings is established, and its effectiveness is confirmed using openly available experimental data. Finally, the electromagnetic coupling among propulsion, levitation, and guidance systems are explored. The findings indicate minimal impact of additional currents in the tube induced by the levitation coils and propulsion windings. This work can provide the reference for the evacuated tube transportation technology in practical application.

集成 EDS 蒸发管运输系统的电磁耦合模拟

超导电动悬浮（SCEDS）在自稳定性、技术成熟度和巨大的悬浮间隙等方面均优于其他技术，因此是与真空管集成的亚声速旅行的最佳选择。然而，真空管道与 SCEDS 列车之间的耦合关系仍然模糊不清。为解决这一问题，本研究通过全尺寸仿真模型研究了它们之间的电磁耦合关系。首先，介绍了集成结构和原理。随后，建立了一个包括电子管、超导磁体、悬浮线圈和推进绕组的仿真模型，并利用公开的实验数据证实了该模型的有效性。最后，还探讨了推进、悬浮和制导系统之间的电磁耦合问题。研究结果表明，悬浮线圈和推进绕组所引起的管内额外电流的影响微乎其微。这项工作可为实际应用中的真空管道运输技术提供参考。
