摘要
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 sludge less orbit seamless switch longitudinal force finite element model Was built, the maybe occurrence situations were calculated with. the model. The calculation results compared with the sludge orbit seamless switch model, the influencing factors of seamless switch temperature force and bit shift, which can be referenced for the sludge less orbit seamless switch construction design.
