东方红内燃机车是我国自行设计生产的干线牵引动力之一,它的各项技术性能在日趋完善中。内燃机车对人的影响是多方面的,据文献报导以及现场工人同志的反映,其对听觉的影响较为突出,对神经系统,心血管系统、消化系统以及植物——内分泌系统、生殖系统等也都有不同程度的影响。为了进一步摸清该型机车的噪声振动规律并提高驾驶室噪声振动控制效果,保护乘务人员身体健康,提高运输生产率,我们于1977年5～6月对某内燃机务段管内的东方红Ⅰ、Ⅱ型内燃机车进行了调查,同时对NY_7型内燃机车作了对照调查。一、噪声振动的特性噪声测量用丹麦B＆K公司的2203型精密声级计与1613型倍频程滤波器,按噪声测量常规方法进
Dongfanghong Diesel locomotive is one of the trunk traction engines designed and manufactured by our country, and its technical performance is improving day by day. The impact of diesel locomotives on people is multifaceted. According to reports in the literature and comrades in the field, the impact on diesel locomotives is more pronounced. For the nervous system, cardiovascular system, digestive system, plant-endocrine system and reproductive system, Have different degrees of influence. In order to further understand the noise and vibration of the locomotive and to improve the control effect of noise and vibration of the cab to protect the health of crew and improve the transport productivity, we conducted an internal combustion engine section of Dongfanghong Ⅰ, Ⅱ Type diesel locomotive was investigated, at the same time a controlled survey of NY_7 diesel locomotive. First, the characteristics of noise and vibration noise measurement with the Danish company B & K 2203 Precision Sound Level Meter and 1613-type octave filter, according to the conventional noise measurement method
