机车车辆车内噪声限值对比分析

Comparison and Analysis on Interior Noise Limit Values of Rolling Stock

为明确不同类型机车车辆的车内噪声控制目标,分析总结相关标准对不同条件下车内噪声限值的要求。按动车类、市域列车类和其他车型对国内不同车型的噪声限值进行了分析,并与国际铁路联盟、欧盟标准噪声限值要求进行对比,有针对性地提出车内噪声限值要求建议,为从事机车车辆低噪声化研发的工程技术人员提供参考。

In order to define the interior noise control objectives of different types of rolling stock,the requirements of relevant standards on the interior noise limit values under different conditions are analyzed and summarized.The noise limit values of different types of vehicles in China are analyzed according to powered car,suburban train and other types of vehicle,and compared with the requirements of the International Union of Railways standards and the European Union standards on noise limit values.Suggestions on the requirements for limit values of noise inside the vehicles are put forward in a targeted way,providing reference for engineers and technicians engaged in the research and development of low noise of rolling stock.
