摘要
基于有限元方法,建立了空间钢桁梁桥上无缝线路梁轨相互作用耦合模型。通过实例,对钢桁梁桥上无缝线路纵向附加力进行计算分析。模型的建立可为今后钢桁梁桥上无缝线路纵向附加力的建模分析提供一种新的思路和方法,并对今后钢桁梁桥上无缝线路设计问题提出一些建议。
Based on the finite element method, a space coupled model of girder-rail interaction of jointless track on steel truss bridge is established, and additional longitudinal force of jointless track on bridge is calculated by a case study. The development of the model provides a new method for research on additional longitudinal force of jointless track on steel truss bridge. Reasonable suggestions are proposed on design of jointless track on steel truss bridge in the future.
