东风_4型交直流电传动大马力内燃机车,现已进行批量生产,这对我国铁路运输事业的发展将起着促进作用。同时,内燃机车的出现为广大机车乘务人员带来了较好的劳动条件,劳动强度大大减轻。但是,机车的噪声振动又成为影响机车乘务人员身体健康的一个突出的新问题。在我们社会主义国家,人是第一可宝贵的因素。因此,当东风_4型内燃机车进入小批量生产的关键时刻,着手研究解决机车噪声振动问题,是十分重要的。即便从机车本身来讲,噪声振动也是衡量机车质量的一个指标,在不断提高机车质量的要求下,降噪减振也是重要内容之一。为此,在部领导的关怀、厂党委的领导
Dongfeng _4 type AC and DC power horsepower diesel locomotive has been mass-produced, which will play a catalytic role in the development of China’s railway transport. At the same time, the appearance of diesel locomotives has brought better working conditions for the majority of locomotive crew and greatly reduced labor intensity. However, the noise and vibration of the locomotive has become a prominent new problem that affects the health of locomotive crew. In our socialist countries, people are the first and most valuable factor. Therefore, when the Dongfeng-4 diesel locomotive enters the critical moment of small-batch production, it is very important to start studying and solving the problem of locomotive noise and vibration. Even from the locomotive itself, noise vibration is an indicator to measure the quality of locomotives. Noise reduction and vibration reduction are also one of the important contents in the continuous improvement of locomotive quality. To this end, the leadership of the Ministry of care, the leadership of the factory party committee
