摘　　要：为降低悬浮能耗,在不改变中低速磁浮列车F型轨道结构和车辆结构前提下,提出一种适合工程应用要求的全尺寸永磁电磁混合磁铁的结构优化设计方法。给出一种永磁体安装于铁心一侧、永磁体极面积可调整的混合悬浮磁铁方案。根据混合磁铁电磁力的非线性模型,分析承载能力与永磁体的厚度、极面积、最大磁能积以及电磁线圈安匝数的约束关系,提出基于有约束的非线性规划策略的混合磁铁的结构优化设计方法。单转向架试验表明,该新型混合磁铁与常规电磁铁的悬浮能力相当,悬浮功耗显著降低。To reduce suspension power loss,a structural optimal design strategy of hybrid magnet with permanent magnet（PM） and electromagnet for middle-low speed maglev train is proposed,without changing the F-type guideway and vehicle structure.A structure scheme of hybrid magnet is presented,that permanent material is placed on one side and the pole area can be adjustable.According to the nonlinear magnetic force expression of hybrid magnet,the restricted relationship about the electromagnet force,thickness and pole area of PM,ampere-turn of electromagnet,and the maximum magnetic energy product of PM is investigated.Then a structural optimal design method of hybrid magnet based on constrained nonlinear programming theory is given.The experiments on a single bogie show that the carrying capability of hybrid magnet is equivalent to that of traditional electromagnet,but the suspension power loss of hybrid magnet is much less.
