列车运行于钢轨上,对钢轨产生纵向力。本文将钢轨作为弹性地基上的连续梁,对钢轨纵向力的计算作初步探讨如下: 铁摩辛柯等编著的《弹性稳定理论》一书,介绍初等弯曲理论。若仅有横向荷重作用于梁时,梁的 The train runs on the rail and creates longitudinal forces on the rail. In this paper, the rail as a continuous beam on the elastic foundation, the longitudinal calculation of the rail force for preliminary study are as follows: Toshosaki and other editors of the “theory of elastic stability,” a book on the elementary bending theory. If only the lateral load acting on the beam, the beam
