铁路运输中的噪声,主要包括机车本身发出的噪声和列车在运行中轮轨发出的噪声。Jenbach工厂对2068型液力传动内燃机车在调车作业中存在的噪声及噪声源进行了大量的试验测量,为降低内燃机车和轮轨噪声提出了一系列措施。而降低噪声措施是否实用,主要看“效益—成本”或“产出—投入”的比例。
The noise in railway transportation mainly includes the noise emitted by the locomotive itself and the noise emitted by the wheel and rail during the operation of the train. The Jenbach factory carried out a large number of test measurements of the noise and noise sources existing in the shunting operation of the 2068 hydraulic transmission diesel locomotive and proposed a series of measures to reduce the noise of the locomotive and the wheel and rail. The noise reduction measures are practical, mainly to see the “benefit - cost” or “output - input” ratio.
