弹性轨道上二自由度磁悬浮列车的动力特性分析

Dynamic Characteristic Analysis of Maglev Vehicle with Two Degrees of Freedom on Flexible Guideways

通过对弹性变形轨道上二自由度磁悬浮列车耦合系统动力特性的数值研究,给出了系统受控稳定性情形下控制参数G1,G2 的选取方式;讨论了控制参数G1,G2 和系统特征参数(如悬浮体质量Ms、运行速度v、轨道跨长L等)对磁悬浮系统的动力学特性的影响方式,分析了弹性轨道的变形特征等。

This paper quantitatively analyzes the selection of the control parameters G 1 and G 2 by means of the numerical simulations for dynamic behavior of a maglev vehicle with two degrees of freedom on flexible guideway, to provide a selecting style of control parameters G 1 and G 2 . Moreover, the effect of the control parameters G 1 and G 2 and the designed parameters(e.g., maglev body mass M 5, moving velocity v and guideway length L) on the dynamic behavior of the magnetic levitated system is discussed and the characters of dynamic deformation of flexible guideway are analyzed for different guideway structure.
