摘要
为了实时有效地对钢弹簧浮置板轨道动力性能进行研究,利用ANSYS软件建立了钢弹簧浮置板轨道系统的双层梁动力学模型,通过瞬态分析模拟列车移动荷载通过钢弹簧浮置板轨道时的动力响应。对比分析了列车荷载作用下,轨道系统参数对钢弹簧浮置板动力响应及其隔振效果的影响。该研究可对钢弹簧浮置板轨道结构的设计与施工提供理论参考。
In order to study effectively the dynamic properties of URT steel spring floating slab track, a double beam dynamics model of steel spring floating slab track system is established based on ANSYS, the dynamic transient response of steel spring floating slab track system is imitated by moving loads. The effect of the system＇s parameters on the dynamic response of steel spring floating slab and the vibration isolation in moving loads is analyzed, which will provide the theoretical reference for the design and construction of steel spring floating slab track structure.
