摘要
有限元仿真分析是常导型高速磁浮列车研究中重要的研究手段之一,针对长定子直线同步电机的有限元模型在网格剖分加密带来的仿真时长增长、计算效率较低的问题,为加快仿真计算速度,提高研究效率,提出一种基于静态参数映射的电机等效电路降阶模型(ECE)。并通过比对等效电路降阶模型与降阶前的有限元模型在全速度范围和不同工况下的仿真结果,验证了降阶模型的准确性,降阶模型极大的提升了仿真计算速度,提高了研究效率。
Finite element simulation analysis is one of the important research methods in the study of conventional high-speed maglev trains.Aiming at the problem of long simulation time and low computational efficiency caused by mesh refinement of finite element model of long stator linear synchronous motor,in order to speed up the simulation calculation speed and improve the research efficiency,an equivalent circuit extraction(ECE)model of motor based on static parameter mapping is proposed.By comparing the simulation results of the equivalent circuit model and the finite element model before reduction in the full speed range and different working conditions,the accuracy of the reduced-order model is verified.The reduced-order model greatly improves the simulation calculation speed and improves the research efficiency.
