建立了无砟轨道无缝道岔纵向受力有限元模型,运用模型计算可能出现的各种工况,得出计算结果,并将所得计算结果与有砟轨道无缝道岔模型进行了对比分析,探讨了影响无缝道岔钢轨温度力与位移的因素,为无砟轨道无缝道岔的施工设计提供了参考。 The longitudinal force finite element model of the seamless turnout of ballastless track is established. The various working conditions that may occur are calculated by using the model, and the calculation results are obtained. The calculated results are compared with that of the ballastless track turnout model. The factors influencing the temperature force and displacement of the seamless turnout rails provide reference for the construction design of the seamless turnout of the ballastless track.
