随着地铁线网的不断增加,地下线路低频噪音对附近居民的影响面越来越大,沿线居民对低频噪音的投诉量逐年递增。低频噪声一直是城市轨道交通工程中难以彻底解决的难题,如何采取措施降低地铁运营产生的低频噪音及共振对附近居民的影响,成为地铁环境问题中亟待解决的问题。本文简要介绍使用螺钉减振器降低二次结构噪音的原理及实际应用分析。
As the metro line network continues to increase, the impact of low-frequency noise from underground lines on residents nearby is increasing. The number of complaints about low-frequency noise among residents along the line has been increasing year by year. Low-frequency noise has always been a difficult problem in urban rail transit projects. How to take measures to reduce the impact of low-frequency noise and resonance caused by subway operations on residents nearby has become an urgent problem to be solved in the metro environment. This article briefly introduces the principle and practical application of screw vibration damper to reduce secondary structure noise.
