Abstract

Accurate analytical calculation of electromagnetic field is the basis of research and optimization of axial magnetic flux eddy current brake, and structural optimization design is the key to improving system performance and reducing engineering construction costs. In order to establish an accurate analytical calculation model of electromagnetic field of axial magnetic flux eddy current brake, based on the two-dimensional analytical calculation model of electromagnetic field, this paper comprehensively considers the influence of non-ideal factors such as core saturation, transverse dynamic end effect and secondary skin effect on the electromagnetic characteristics of axial magnetic flux eddy current brake, and obtains an improved analytical calculation model of electromagnetic field by introducing corresponding correction coefficients, and verifies the accuracy of the analytical calculation model of electromagnetic field by comparing with the numerical calculation results of three-dimensional electromagnetic field finite element model. On this basis, an improved multi-objective particle swarm optimization algorithm is adopted to optimize the system design, so as to increase the electromagnetic braking torque, reduce the electromagnetic axial force and reduce the secondary mass. Finally, the accuracy of the above electromagnetic field analytical calculation model and optimization design results is verified on the experimental research platform of axial magnetic flux eddy current brake, which can provide theoretical basis for subsequent researchers to design and optimize the electromagnetic scheme. © 2025 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.

考虑非理想因素的轴向磁通涡流制动器电磁场建模与优化设计

准确的电磁场解析计算是轴向磁通涡流制动器研究与优化的基础，结构优化设计是提高系统性能、降低工程建设成本的关键。为了建立准确的轴向磁通涡流制动器电磁场解析计算模型，本文在二维电磁场解析计算模型的基础上，综合考虑了磁芯饱和、横向动端效应和二次集皮效应等非理想因素对轴向磁通涡流制动器电磁特性的影响。通过引入相应的修正系数，得到了改进的电磁场解析计算模型，并通过与三维电磁场有限元模型的数值计算结果对比，验证了电磁场解析计算模型的准确性。在此基础上，采用改进的多目标粒子群优化算法对系统进行优化设计，以增大电磁制动力矩，减小电磁轴向力，减小二次质量。最后，在轴向磁通涡流制动器实验研究平台上验证了上述电磁场分析计算模型和优化设计结果的准确性，为后续研究人员设计和优化电磁方案提供理论依据。©2025日本电气工程师协会和Wiley期刊有限责任公司。
