本文提出一个轨道强度计算的静力模型和相应的计算方法。其中假定钢轨向下挠曲时所受的是支点反力;向上挠曲时所受的是扣件反力(由于轨枕自重和轨枕与道床的摩擦力),这两种反力按上下方向以不同的非线性关系依赖于钢轨位移。在结论部分给出了按Winkler假设和本文方法计算结果的比较。
In this paper, a static model of track strength calculation and corresponding calculation method are proposed. Which assumes that the downward deflection of the rail is subjected to the fulcrum reaction force; when the upward deflection is subjected to the reaction force of the buckle (due to the self-weight of the sleeper and the friction between the sleeper and the track bed) The different non-linear relationship depends on the rail displacement. In the conclusion part, the comparison between the Winkler assumption and the calculation results of this paper is given.
