摘要
文章基于有限元理论,建立弹性长枕整体道床结构计算模型,模拟了落轴试验的整个过程,对轨道的动力特性及减振性能进行分析,分析轨下刚度的合理范围,为弹性长枕整体道床结构的养护维修、铺设和设计提供指导。
Based on the finite element theory, the paper sets up calculation model for slab track structure with elastic long sleeper and it simulates whole process loaded test. The dynamic characteristics of track and damping performance are analyzed. Meanwhile the proper range of the under-rail stiffness is also analyzed, so the paper provides guidance for maintenance, installation and design of slab track structure with elastic long sleeper.
