基于有限元软件ANSYS，以12号桥上无缝道岔为例，通过ANSYS的APDL参数化建模技术，建立桥上无缝道岔计算模型，计算了12号无缝道岔的受力与变形，并分析了道岔在桥上相对位置不同时对无缝道岔受力与变形的影响。对桥上无缝道岔的设计和养护维修有一定的指导意义。%Based on the finite element software ANSYS, taking No.12 seamless turnout on the bridge as an example, through ANSYS APDL parametric modeling technology, seamless turnout on the bridge calculation model was established. Meanwhile, the force and displacement of the 12 seamless turnout were also calculated and analyzed when seamless turnout and bridge relative position was changed. It has certain guiding significance to design and maintenance of bridge.
