【摘要】 工业噪声是当今主要公害之一,对其进行防治或控制相当重要。风机是我国目前工业生产中应用十分广泛的设备之一,其在运转过程中发出十分强烈的噪声会带来严重的噪声污染问题,因此风机噪声控制技术一直受到广泛关注。本文以降低工业风机噪声为目标,在参考国内外最新研究的基础上,对工厂中风机噪声的控制技术作了简要综述,着重介绍了叶片周向角的不等距布置,有源噪声控制等技术,并且讨论了研究中存在的一些问题及进一步的工作。更多还原

【Abstract】 Industrial noise is one of the main social effects of pollution nowadays.It is much important to prevent and control it.And blower is one of the equipments being used extensively during the industrial production in our country presently.Intense noise emitted in operation can cause serious noise-pollution problem.So the technology of blower noise control has all the time attracted broad attention.In order to reduce the industrial blower noise,with the reference to upto-date world wide literatures,some methods based on unequal spacing blades and active noise control are emphatically presented on with a concise review of conventional methods of industrial blower noise control.The applications of the methods in engineering are presented,and some problems and further research work of the methods are discussed.更多还原
