摘要

交通系统的运营诱发的环境振动已成为人们普遍关注的问题。现场测试是研究环境振动问题主要途径之一,而大量本底振动的影响使测试数据不能真实反应所测试振源及传播的特点。为保证测试数据准确性,从加速度时程和加速度振级两个方面提出了消除本底振动影响的两种方法,即幅值修正法和加速度振级修正法;通过现场测试数据进行了对比分析,结果表明两方法均可达到预期效果;最后在此基础上探讨了是否需要消除本底振动的基本判定原则。

Abstract

Environment effects due to traffic transmit is paid more and more attention nowadays. In suit experiment is one primary approach to this problem, but because of mass background vibration, the testing data can not represent the vibration characteristic of source and promulgation. In order to obtain ideal data, two methods to remove background vibration were presented in this paper, one was Fourier Amplitude Revised Method, the other was Acceleration Vibration Level Revised Method, the two methods were tested in measured data, the result showed that the two methods were effective. Basic principles to banish background vibration were discussed in the end.
