摘要
针对铁路噪声污染状况,根据提速列车运行噪声的特点及轮轨噪声产生的机理,研究了通过在钢轨轨腰镶嵌高阻尼材料从而降低轮轨噪声的技术。经过实验室试验和现场安装试验,证明该技术可有效降低轮轨辐射噪声。
In order to alleviate the problem of railroad noise pollution, this paper studies the wheel-rail noise reducing technology by sticking high damping materials on the two sides of rail according to the characteristics of train running noises after speed increase and wheel-rail noise generating mechanism. After lab test and onset installation test, it has been proved that this technology can effectively reduce the wheel-rail radiation noise.
