| 摘要: |
| 为了改善磁悬浮汽车的基础性能,基于目前国内外永磁电动悬浮的研究现状,提出了一种基于更优磁化角的永磁电动轮结构。首先从原理的角度分析磁化角度变化实现更优电动轮结构的理论合理性,通过优化环形永磁电动轮的磁化角可以增加单极对的永磁体数量增加外围磁场强度,并利用等效面电流法推导得出更简洁的解析计算公式,分析得到了永磁电动轮与导体板之间的结构关系、磁场特性和涡流分布特点；然后在三维电磁仿真优化方面,从磁场、悬浮力、驱动力、浮重比和浮驱比等多个性能参数对比传统的永磁电动轮和改进的永磁电动轮。结果验证了改进后的永磁电动轮结构对其悬浮-驱动一体化功能具有有益提升,并从解析计算和实验分析两个角度共同验证三维电磁仿真的准确性和可靠性,为后续设计优化工作提供了可靠手段。这种Halbach阵列永磁电动轮的优化方案有助于磁悬浮概念车的基础性能提升,为“碳达峰、碳中和”背景下新型绿色环保交通工具的形成提供了可行的技术选择。 |

| Abstract: |
| To improve the basic performance of the magnetic levitation car, based on the current research situation of permanent magnet electrodynamic suspension (PMEDS),this paper propose a better annular structure of permanent magnet electrodynamic wheel(PMEDW). In term of theoretical analysis, this paper analyzes the theoretical rationality of Halbach array magnetization varying by different magnetization angle, the number of permanent magnets in the monopole pair can be increased to increase the peripheral magnetic field intensity by optimizing the magnetization angle, a more concise analytical formula is derived by using the equivalent surface current method, and the structural relationship, magnetic field characteristics and eddy current distribution characteristics between the PMEDW and the conductor plate are obtained through analysis. In terms of 3D simulation optimization, different types of PMEDW were established in ANSYS Maxwell. The magnetic field, levitation force, propulsion force, levitation to weight ratio and levitation to propulsion ratio were compared respectively in simulation analysis and analytical calculation results to verify whether the new type of PMEDW is able to improve the function of levitation-propulsion integration simultaneously, the accuracy and reliability of the 3D electromagnetic simulation are verified from the perspectives of analytical calculation and experimental testing. The optimization scheme of Halbach array permanent magnet electric wheel will contribute to improve the basic performance of the magnetic levitation concept car, and provide a feasible technical choice for the formation of new green and environmentally friendly vehicles under the background of "emission peak and carbon neutrality". |
