摘要
通过分析列车过桥过程中的耦合振动,提出了不同刚度弹性支座在车桥系统减振中有何作用的问题,并采用ANSYS软件进行仿真计算,得出桥梁在使用不同竖向刚度的弹性支座时的减振效果。结果表明:支座的竖向刚度取300 k N/mm比较适宜,对整个桥梁的竖向减振最有利。
In this paper,the coupling vibration of train passing through the bridge is analyzed,and the effect of elastic bearings on the vibration reduction of the whole train-bridge system is put forward.And ANSYS software is used to simulate and calculate the vibration reduction effect of the bridge when using elastic bearings with different vertical stiffness.The results show that the vertical stiffness of the bearing 300 kN/mm is more suitable for the vertical vibration reduction of the whole bridge.
