摘要
探索了一种用于高架桥轨道交通系统噪声源识别的方法,该方法以ISO测量标准为依据,并针对上海现行的高架桥轻轨系统。介绍了测量高架轨道噪声的方法和识别轨道噪声源的原理,详细研究了轨道主要噪声源的分布规律,并进行了实地测量实验。实验结果正确可靠,为提供现行高架轨道系统的减振降噪措施提供了依据。
This paper has explored a kind of method to discern the source of the noise from viaduct transportation system. It bases on ISO measurement standard, and directs against the current system of light railway viaduct in Shanghai. This paper introduces the method to measure the track noise and principle on how to distinguish the main noise source, researches the distributing law of the main noise source, and does the experiment on the spot of the light railway viaduct. It is reliable that the experimental result is correct, and the basis for the reduction of the vibration and noise on viaduct transportation system has been offered.
