摘　　要：为解决北京地铁6号线部分区段列车通过时轨道的啸叫噪声,在北京地铁6号线物资学院路站—通州北关站区间上行K33+180~K33+340处安装谐振式钢轨阻尼器,安装前后未对钢轨进行打磨处理。为验证其降噪效果,在阻尼器安装前后分别进行客室噪声、司机室噪声、轨旁噪声、钢轨振动加速度对比测试,其降噪效果达到要求。In order to solve the track screeching noise of Beijing metro line 6,the resonant rail damper is installed in the east bound from Beijing Wuzi university road(K33+180~K33+340)to Tongzhou beiguan in Beijing metro line 6.The rail is not ground before and after installation.In order to verify its noise reduction effect,the passenger compartment noise,cab noise,way-side noise,rail vibration acceleration has been tested for comparison before and after the damper installation,and as a result the noise reduction effect meet the requirements.
