摘要
本文以实际案例为背景,分析了列车下穿既有桥梁的振动安全状况。首先利用动力传感器采集了列车经过桥梁时的承台振动信号;然后建立了有限元软件,并分析了桥梁各阶振动频率;最后采用时程分析和反应谱分析两种方法,分析了列车穿过时桥梁的振动情况。
In this paper, the vibration safety condition of the train passing through the existing bridge is analyzed under the background of the actual case. Firstly, dynamic sensor train bridge vibration signal after cap; Then established the finite element software, and analyzed the vibration frequency of bridge; Finally, the time history analysis and response spectrum analysis of two methods, analyzes the vibration when the train went through the bridge.
