摘　　要：本文将板式无砟道岔系统视为梁-实体-实体组合结构体系,通过Ansys软件建立板式无砟道岔道床的空间有限元模型,采用ADAMS/Rail软件进行岔区结构不平顺仿真,计算了列车过岔的动力响应;选取合适的计算参数,计算分析了转辙器区和辙叉区道床板及底座板的受力变形,为板式无砟道岔的设计、施工提供参考。In this paper,considering slab ballastless turnout system as the beam-entity-entity composite structure system,a spatial finite element model was established by Ansys software.The constructed irregularity of turnout area structure was simulated by ADAMS/Rail software,and the dynamic response of the track structure was calculated when the train running through the turnout;The paper analyzed the stress and deformation behavior of the bed board and the base plate in the area of switch and frog by selecting the appropriate calculation parameters.And it provided a theoretical reference for the design and construction of slab ballastless track.
