摘要
对长定子中低速磁浮列车轨道结构进行了较全面的动力学有限元数值分析,获得了长定子中低速磁浮列车轨道结构的动力学基本品质特性,即磁浮轨道固有频率和振动模态。在此动力学有限元数值分析基础上,研究分析了磁浮轨道对振动比较敏感的频率范围并进行了优化设计。结果表明,对长定子中低速磁浮轨道有限元数值分析不仅在理论上起到了检验与校核的作用,为长定子中低速磁浮列车调试实验提供了磁浮轨道结构的计算数据,还对磁浮轨道性能的进一步设计和优化提供了依据。
The long stator of medium and low speed maglev vehicle track structure undertook more comprehensive dynamic FEM numerical analysis,obtaining the dynamic characteristicsthe of long stator of medium and low speed maglev vehicle track structure,namely,natural frequency and vibration mode of Maglev track.On the basis of this dynamic finite element numerical analysis,the research is done to analyze maglev track on vibration sensitive frequency range and optimization design.The results show that,for long stator of medium and low speed maglev rail,finite element numerical analysis not only plays the role of testing and calibration theoretically,but it also for long stator of medium and low speed maglev vehicle debugging experiments provides the calculation data for maglev track structure,and also provides basis for further performance design and optimization of the maglev track.
