The traditional permanent magnet electrodynamic suspension (PMEDS) structure has a high cost and low lift to drag ratio caused by sizeable magnetic resistance, which limits its widespread use. Hence, an annular Halbach structure of permanent magnet electrodynamic wheel (EDW) is studied in this paper, which is able to convert the magnetic resistance into the thrust force and avoid extra energy consumption, thus have the potential to be applied into the maglev car system. This paper established an experimental platform to measure the levitation force and thrust force of the EDW, then the force characteristics and variation tendencies were analyzed. Next, to verify the effectiveness and accuracy of the experiment, the comparison between force results from the experiment and that from the 2D FEM simulation were studied. Eventually, this paper lays a foundation for further research on the dynamic levitation characteristics of the EDW. And it provides an individual experimental basis and theoretical guidance for the study of maglev cars based on the PMEDS principle.

磁悬浮车用永磁电动轮悬浮力和推力特性分析与试验

传统的永磁电动悬架（PMEDS）结构由于磁阻较大，造价高，升阻比低，限制了其广泛应用。因此，本文研究了永磁电动轮（EDW）的环形Halbach结构，该结构能够将磁阻转换为推力，避免额外的能量消耗，因此具有应用于磁悬浮汽车系统的潜力。 . 本文建立了一个实验平台来测量EDW的悬浮力和推力，然后分析力的特性和变化趋势。接下来，为了验证实验的有效性和准确性，研究了实验和二维有限元模拟的力结果之间的比较。最终，本文为进一步研究EDW的动态悬浮特性奠定了基础。并为基于PMEDS原理的磁悬浮汽车的研究提供了个性化的实验依据和理论指导。
