摘要:
为提升横向稳定性这一限制中低速磁浮车辆提速的重要因素，以F型导轨和倒U型导轨为对象建立其二维电磁有限元模型和三维变形仿真模型，利用该模型对比研究这两种典型导轨的磁场分布、电磁力及变形特性，并提出导向刚度系数这一新的评价指标来评估磁浮系统的导向性能。揭示了导向刚度系数与磁极宽度之间的相关性，明确了降低磁极宽度对导向性能的增益效应。从磁力特性、变形和导向性能三个方面总结出导轨结构型式和参数的改变对磁浮系统横向稳定性的影响，为适用于更高速度下的导轨结构设计提供了参考。
Abstracts:
A two-dimensional electromagnetic finite element model and a three-dimensional deformation simulation model of F-shaped rail and inverted U-shaped rail are established to improve the lateral stability, which is an important factor limiting the speed increase of medium-low speed maglev vehicles. The magnetic field distribution, electromagnetic force and deformation characteristics of the two typical rails are compared and studied by using these models. A new guiding performance evaluation index is proposed, which is named guidance stiffness coefficient. The correlation between the guidance stiffness coefficient and the magnetic pole width is revealed, and the gain effect of reducing the magnetic pole width on the guiding performance is clarified. The influence of rail structure format and parameters on the lateral stability is summarized from three aspects of magnetic force characteristics, deformation and guiding performance, which provides reference for rail structure design suitable for higher speed.
