摘要
将轨道结构简化为弹性支承交叉地基梁系,建立了有碴轨道结构路桥过渡段的空间计算模型,采用ANSYS有限元分析软件对过渡段结构进行了静力分析,并对不同的竖向支承刚度比时过渡段钢轨及轨枕的应力及位移进行了讨论。
The track structure is simplified as the elastically supported grillage girder. A space model of the track on roadbed - bridge transition section is established. The structure of the track on roadbed-bridge transition section is analyzed with the finite element analysis software ANSYS. The distribution of stress and displacement near the transition section are discussed for different stiffness ratios.
