摘要
噪声防治是城市轨道交通面临的一大课题,而控制轮轨噪声则是从源头来治理轨道交通噪声。文章对北京地铁车辆的轮轨噪声进行了测试和分析,并率先在地铁13号线车辆上采用了车轮降噪阻尼器,通过对比实验表明它对消除中高频轮轨噪声具有明显的作用。
Noise control is a big challenge in urban mass transit system.The noise of it mostly comes from wheel/rail vibra tion.This paper tests and analyzes the wheel/rail noise,and firstly put s forward the using of the wheel vibra-tion ab sorber on vehicles of Beijing Metro Line13.The noise level with wheel vibration ab sorber is much low er than that with out wheel vibration absorber.The tests indicate that the wheel vibration absorber has great effect on re ducing wheel squeal noise.
