研究钢轨在纵向温度力的作用下无缝线路轨道的动力特性。通过建立无缝线路轨道模型来分析温度力变化对振动模型及谐振频率产生的影响 ,以及轨道参数如钢轨类型、支座刚性和轨枕间隔距的变化对振动特性的影响。并得出一些初步的结论。
The dynamic characteristics of the track of CWR under longitudinal temperature force are studied. Through the establishment of a seamless track model, the influence of the temperature variation on the vibration model and the resonant frequency is analyzed. The influence of the orbital parameters such as the type of track, the stiffness of the support and the spacing of sleepers on the vibration characteristics is analyzed. And draw some preliminary conclusions.
