Modeling and Electromagnetic Performance Analysis of the Combined Propulsion Levitation and Guidance Superconducting Electrodynamic Suspension Maglev Train
牵引悬浮导向一体化超导电动磁浮列车实现了一种地面线圈提供三维电磁力,对于降低建造成本和缩短周期具有重要意义.基于空间谐波法建立了牵引悬浮导向一体化电动磁浮列车数学模型,计算列车的磁感应强度以及电磁力.然后,建立了列车单侧的有限元模型,对空间谐波法进行验证.最后,基于对称模型,改变上下线圈高度成为非对称模型,设计非对称系统系数,研究起浮与稳定运行时的牵引、悬浮和导向电磁特性,结果表明非对称系统的悬浮特性更好,而对称系统的牵引性能更好,为牵引悬浮导向一体化电动磁浮列车的设计与优化提供理论基础.
The combined propulsion,levitation,and guidance superconducting electrodynamic suspension maglev train is capable of achieving electromagnetic forces generated by ground coils,which is of significant importance for reducing construction costs and shortening development cycles.A mathematical model of the maglev train was established based on the space harmonic method,and the magnetic flux density and electromagnetic forces of the train were calculated.Then,a single-side finite element model of the maglev train was developed to validate the space harmonic method.Finally,an asymmetric model was designed by changing the heights of the upper and lower coils,based on the symmetrical model.An asymmetric system coefficient was introduced to investigate the propulsion,levitation,and guidance electromagnetic performances during lift-off and stable operation.The results indicated that the asymmetric system exhibited superior levitation performance,whereas the symmetric system demonstrates better propulsion performance.The findings of this analysis provide a theoretical foundation for the design and optimization of the combined propulsion,levitation,and guidance electrodynamic suspension maglev train.
