摘要：采用仿真分析与实验验证相结合的方法研究了横向磁通磁悬浮直线电机的自稳定能力及其电磁力特性。建立横向磁通磁悬浮直线电机三维电磁计算模型，利用有限元软件研究了电机次级电流分布以及电磁轨道几何参数、电气参数对电机性能的影响规律。研制实验验证样机，利用搭建的实验平台，测试在不同励磁电流大小、频率和悬浮气隙的条件下，电机次级所受到的驱动力、悬浮力、导向力的变化情况，并与仿真结果对比，验证有限元仿真模型的有效性与准确性,为横向磁通磁悬浮直线电机在轨道交通等领域的应用提供理论支撑。

Abstract: This paper studied the electromagnetic forcescharacteristics of transverse flux linear motor (TFLM) based on simulation analysis and experimental verification. A 3D finiteelement model has been built to evaluate the dependence of the performance of the TFLIM on the geometries of electromagnetic rail,electrical parameters and air gap.Laboratory prototype and experiment platform have been finished.The thrust,suspension forceand guidance force of the TFLIM were tested under different exciting currents,frequencies and air gaps.Comparisons between simulation and experiment have verified the accuracy and validity of the finiteelement model.This paper can provide theoretical support for the technical development and applications of the TFLM in magnetic levitation trains.
Key words: transverse flux linear motor (TFLM); finiteelement analysis;magnetic levitation trains |
