基于动力有限元和耦合振动理论建立了高速磁浮列车-轨道梁动力学模型,通过仿真计算得到了随机不平顺对系统动力指标影响规律,随机振动功率谱分析结果表明了理论计算的有效性。通过此项研究,为进一步探讨高速磁浮铁路列车与轨道相互作用问题、完善磁浮线路设计及养护维修工作打下良好的基础。
The dynamic model of high-speed maglev train-track beam is established based on the theory of dynamic finite element and coupled vibration. The influence of random irregularity on the dynamic index of the system is obtained by simulation calculation. The results of random vibration power spectrum analysis show the validity of the theoretical calculation. Through this study, in order to further explore the high-speed maglev railway train and track interaction problems, improve Maglev line design and maintenance work laid a good foundation.
