摘要
电磁力准确计算是对Halbach阵列永磁电动悬浮系统进行研究和优化的基础,结构优化是提高系统性能和减少工程化建设成本的关键。建立包含类似直线电机横向端部和纵向端部效应的三维电磁场解析模型,通过对比2-D、3-D解析模型计算结果与3-D有限元仿真结果,验证了所建解析模型的准确性和可靠性。基于三维解析模型对永磁电动悬浮系统进行优化分析,研究结构参数对优化指标的影响,首次量化导体板宽度和永磁体宽度对系统横向端部效应的作用,总结出基于参数分析的系统优化设计方法。最后利用多目标粒子群优化算法对系统进行优化,通过对比参数分析系统优化设计解和优化算法设计解的性能,证明提出的优化方法快速可靠。
The accurate calculation of electromagnetic force is the principle of analysis and design for permanent magnet electrodynamic suspension(PM-EDS)system with a Halbach array and optimization is the key of enhancing system performance and reducing construction cost.The 3D analytical model including the transverse edge effect and longitudinal end effect,well known for describing linear induction machines,was established in this paper.The comparison of different calculation results between 2-D,3-D analytical models and 3-D FEA simulation results reveals that the presented model is accurate and reliable.The impact of structure parameters on optimization objectives was studied through optimization analysis of PM-EDS based on 3D analytical model,where the influence of the conductive plate width and permanent magnet width on the transverse edge effect was first analyzed.And a system optimization design method based on parameter analysis had been drawn.Finally the multi-objective particle swam optimization(MOPSO)was performed utilizing the 3D analytical model.The high efficiency and reliability of the optimization method presented is validated by comparing the performance of design given by proposed optimization method and that given by MOPSO.
