针对一种轨枕与钢轨连成一体,通过轨枕互相铰接而形成轨道,依靠设在轨枕端部的传动轴传递扭矩并实现轨道整体弯转的新型柔性轨道构造方案,研究了这种柔性轨道弯曲变形的规律。推导了柔性轨道受力弯曲的端部偏移量、轨向角变化量、钢轨轨缝变化量等主要轨道形变参数与相关设计参数之间的函数关系。对主要形变参数进行数值计算与分析,从几何变形关系及其数值分析方面证明这种新型柔性轨道设计方案的可行性,并给出其主要设计参数的参考值。
A kind of new type flexible track construction scheme that the sleeper is integrated with the rail, hinged to each other by the sleepers, the transmission torque is provided by the transmission shaft provided at the end of the sleeper and the whole track is bent is studied, and the bending deformation of the flexible rail is studied The law. The functional relationship between the main orbit deformation parameters and the related design parameters such as the deflection of the flexible rail subjected to bending and bending, the variation of the orbital angle and the variation of the rail slippage are derived. The main deformation parameters are calculated and analyzed numerically. The feasibility of this new flexible track design scheme is proved from the relationship between geometric deformation and its numerical analysis. The reference values of the main design parameters are also given.
