Modeling and Electromagnetic Performance Analysis of the Combined Propulsion Levitation and Guidance Superconducting Electrodynamic Suspension Maglev Train
摘要
Abstract
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.关键词
