温度荷载下Ⅰ型板式无砟轨道对无缝线路的影响研究

Research on influence of CRTS Ⅰ ballastless track on CWR under temperature loads

基于有限元软件ANSYS,建立了轨—板—桥—墩一体化模型,研究了温度荷载下轨道板的受力变形以及对无缝线路的影响,指出随着温度的升高和温差的增大,轨道板的受力变形和对无缝线路的影响增加。

Based on the finite element software ANSYS,a integrated CRTS I ballastless track model including “ rail- slab- bridge- pier” was estab-lished and the interaction relationship between ballastless track and CWR was considered. The force and deformation of the slab and CWR were analyzed under different temperature loads. The results show that, with the increase of temperature and the temperature difference, the deforma-tion and force of the slab and the influence on CWR increased.
