针对高速磁浮列车在运行过程中电磁力难以直接测量的困难,采用有限元分析软件AN-SYS建立了悬浮电磁铁的二维模型,并对模型进行了有限元分析与计算,得到了其内部的磁力线分布情况以及磁浮列车在不同运行情况下的电磁力数据,并总结了推力和悬浮力随功率角、气隙、定子电流和转子电流的变化规律,在此基础上采用最小二乘法建立了指数形式的电磁力软测量模型。采用该模型,列车在运行过程中所产生的电磁力可以通过气隙、定子电流和转子电流的测量结果计算得到。该模型的最大误差小于1%,为高速磁浮列车运行过程中电磁力的计算和控制提供了重要依据。
Aiming at the difficulty of direct measurement of electromagnetic force in high-speed maglev train during operation, a two-dimensional model of suspension electromagnet was established by finite element analysis software AN-SYS, and the finite element analysis and calculation of the model were carried out. The internal The distribution of the magnetic flux and the electromagnetic force data of the maglev train under different operating conditions. The variation law of thrust force and suspension force with the power angle, air gap, stator current and rotor current are summarized. Based on this, The form of electromagnetic force soft-sensing model. Using this model, the electromagnetic force generated by the train during operation can be calculated by measuring the air gap, stator current and rotor current. The maximum error of the model is less than 1%, which provides an important basis for the calculation and control of the electromagnetic force during the operation of high-speed maglev train.
