摘要
隔离式道床垫作为一种新型的轨道减振产品,近年来,在国铁和城市轨道交通建设中得到了广泛的应用。本文通过建立隔离式减振垫的有限元模型,研究其固有频率和动力学响应,分析隔离式道床垫的减振性能,为实现减振轨道结构的合理选用提供参考。
The isolation damping pad,as a new product used to reduce track vibration,has been used widely in national railway and rail transit systems in recent years.The paper establishes the finite element model of isolation damping pad to study its natural frequency and dynamic response,and analyzes its damping performance.The study results would provide a reference for selection of anti-vibration track structure.
