摘要
根据跨区间无缝线路无缝道岔的三种常见的组合情况,建立了无缝道岔组合作用体系的计算模型。采用无缝道岔结构体系分析广义变分原理,建立无缝道岔组合作用体系的平衡方程,计算和分析了无缝道岔组合作用体系的钢轨附加纵向力及位移,研究结果对无缝道岔组合作用体系的设计、养护维修有一定指导意义。
According to three kinds typical welded turnout combination system, a mechanical model of welded turnout combination system has been established. Based on generalized varaitional methods of railway welded turnout, the equilibrium equation of welded turnout combination system is derived, and the additional temperature forces and the displacements of rails is computed. The results can be used to guide the design and the maintenance of continuous welded turout.
