桥上无缝线路伸缩力计算模型研究

Study on computational models for expansion and contraction force of jiontless rail on bridge

介绍了桥上无缝线路伸缩力的计算方法 ,可直接根据以往的试验和计算结果 ,拟定钢轨伸缩力的变形函数 ,再根据钢轨位移和伸缩力的微分关系得到钢轨的位移函数 ,从而结合结构的边界条件和变形协调条件得到所需的解答。

In this paper the calculation method of expansion and contraction force is introduced for jiontless rail on bridge. And according to former experimental and calculation results, the differential relationship between rail displacement and expansion and contraction force the displacement function is acquired as well as the expected solutions based upon boundary conditions of structure and compatibility condition of deformation.
