高速铁路路基有砟轨道与无砟轨道过渡段的特性影响着列车线路的稳定性,这一研究对于列车的平稳运行和乘客的安全尤为关键。本文首先对国内外关于有砟轨道和无砟轨道的研究现状进行了分析,接着介绍了有限元模型和其求解与建模方法可靠性的验证;再次对过渡段动力学特性和优化方案设计进行了研究,以期为列车的平稳运行提供参考和借鉴。
The characteristics of high-speed railway embankment ballastless track and ballastless track transition section affect the stability of train lines. This research is particularly important for the smooth operation of train and the safety of passengers. This paper first analyzes the current research on ballastless orbital orbit at home and abroad, then introduces the finite element model and the verification of the reliability of the solution and modeling method. Thirdly, the dynamic characteristics of the transition section and the design of the optimization scheme Study, in order to provide a reference for the smooth operation of the train.
