摘要
利用ANSYS软件,建立了浮置板轨道系统的有限元模型。采用Newmark时间积分方法,模拟了列车荷载作用下,浮置板轨道结构的瞬态响应。分析表明,浮置板轨道的隔振效率远优于普通板式轨道,弹簧隔振器的刚度、阻尼等参数对浮置板的振动特性影响较大。
Floating track bed system (FTS) is a new anti-vibration track system. FTS finite element model was established by ANSYS. Transient response was simulated under the train vibration load by means of Newmark time integration. It was found that the isolation efficiency of FTS greatly exceeded that of general slab track,and parameters,including the spring rigidity and damp,have a deep influence on the characteristics of FTS.
