摘要:
钢弹簧浮置板轨道是地铁中常用的减振轨道结构之一,该种轨道结构利用螺旋钢弹簧把轨道结构与基础分开,使轨道板处于悬浮状态,将轨道板振动隔离。本文建立钢弹簧浮置板轨道板有限元模型与传统地铁无砟轨道有限元模型;在该模型中考虑了隧道以及大地的影响,同时使用粘弹性人工边界条件来模拟大地的无限长特性,在轮轨粗糙度激励下,对比分析了钢弹簧浮置板轨道结构和传统地铁无砟轨道结构的振动特性以及钢弹簧浮置板的减振效果。

Abstract: Steel spring floating slab track is one of the common tracks of vibration reduction used in metro. The steel spring separates track structure and its foundation, which makes the slab instate of suspension to isolate vibration. In this paper, the finite element model of steel spring floating slab track and the traditional ballastless track of metro is established. In the model, the tunnel and ground are considered, and the visco-elasticartificial boundaries are used to simulate the infinite characteristic of the ground. In the excitation of wheel-rail roughness, the vibration characteristic of steel spring floating lab track is analyzed, and vibration reduction effect of steel spring floating slab track is compared to that of the traditional ballastless track of metro.
