采用有限单元法对菱形交分渡线不同扣件刚度下心轨顶宽20 mm和50 mm处进行了强度分析,得出在列车荷载作用下不同扣件刚度对心轨的承载力的影响,为研发菱形交分道岔区轨道扣件提供了参考。
The finite element method was used to analyze the strength of the top of rail with 20 mm and 50 mm under the different fastener stiffness of the rhombus transitional line. The influence of different fastener stiffness on the bearing capacity of the rail was obtained Research and development of diamond cross-track turnout rail fastener provides a reference.
