摘要
噪声污染已经变成和大气污染、固体污染、水污染并列的一种影响城市环境和居民工作生活的一种污染源。而舷外机作为现在人们生活水上出行最重要的交通工具,其噪声污染源占到总噪声污染的比重很大,因此对舷外机噪音的控制尤为重要。而内燃机噪声中不同的噪声污染识别分离,对于整个内燃机设计及舷外机整体构造具有重要的意义,本文以机械噪声和燃烧噪声为切入点,对其具体的识别分离方法进行分析,并提出对应的噪声控制措施。
Noise pollution has become a pollution source that affects the urban environment and residents'work and life in parallel with air pollution,solid pollution and water pollution.As the most important means of transportation for people to travel on water,the noise pollution source of outboard aircraft accounts for a large proportion of the total noise pollution.Therefore,the control of outboard aircraft noise is particularly important.The identification and separation of different noise pollution in internal combustion engine noise is of great significance for the whole internal combustion engine design and the overall structure of outboard engine.Taking mechanical noise and combustion noise as the starting point,this paper analyzes the specific identification and separation methods,and puts forward the corresponding noise control measures.
