摘　　要：针对北京地铁机场线进口直线电机车辆维修成本高、售后服务迟缓、购买备品备件困难等问题,开展了具有自主知识产权的大功率强迫风冷式直线感应电机轨道交通车辆的研究。就车辆电机研发过程从理论上推导了直线感应电机修正的T型等效电路,通过有限元分析电磁特性提出了一种新的电磁设计程序算法。在此基础上利用现代电机设计技术,采用电磁场和电路计算等手段,对大功率牵引直线电机的电磁参数和机械结构参数进行优化设计和计算。仿真与试验结果表明,自主研发的国产化直线感应电机具有良好的加减速性能,其力特性及电特性满足设计要求,提出的电磁设计程序和控制策略可行。安装了研制电机的直线电机轨道交通样车在各种工况下均能在试验线上可靠稳定运行。Aiming at solving the maintenance problems, such as high cost, slow service, difficulties to buy spare parts, of imported vehicles for Beijing Subway Airport Line, the domestic research of subway vehicles with forced air-cooled and high-power linear motor was investigated. Theoretically, a modified T-type equivalent circuit of linear induction motor for subway vehicle was derived. Then a novel program algorithm for electromagnetic characteristics design was proposed with finite element analysis method. On this basis, applying modern motor designing technology, the electromagnetic parameters and mechanical structure parameters for high-power linear motors were optimized by means of electromagnetic and circuit calculation. The simulation and experimental results show that the linear induction motor independent localization researched has excellent acceleration and deceleration performance, and that the strength characteristics and electrical characteristics meet the design requirements. The feasibility of the proposed control scheme is verified. The vehicle installed the linear motor developed can be running reliably and stably in various conditions.
