运用梁板岔互作用原理,在考虑岔、板、桥和墩台相互作用的基础上,建立适用于各种跨度简支梁、连续梁、刚构桥上的“岔—板—桥—墩”一体化计算模型,可用于对桥上纵连板式无缝道岔伸缩附加力、制动附加力、断轨力、梁轨相对位移及墩台纵向受力和变形的计算分析;为便于计算,以有限元软件ANSYS为计算平台,利用ANSYS参数化设计语言进行二次开发,编制了桥上纵连板式无缝道岔计算软件,适用于各类型桥上道岔群的设计计算。
Based on the principle of beam-plate interaction, the interaction between the bifurcation, plate, bridge and piers is established based on the interaction between the bracing beams, the continuous beams and the rigid-framed bridges. Pier "integrated calculation model can be used to calculate and analyze the expansion and contraction additional force, the additional braking force, the track-breaking force, the relative displacement of the beam-track and the longitudinal force and deformation of the abutment on the continuous connected plate-type seamless turnout. The finite element software ANSYS was used as the calculation platform, and the secondary development was carried out by ANSYS parametric design language. The calculation software of the bridge-connected slab-type seamless turnout was developed. It is suitable for the design and calculation of the turnout group of all types of bridges.
