摘要
本文以某轮式装载机为样机,在进行大量试验的基础上,对影响驾驶室内噪声的主要噪声源和驾驶室本身的声学特性进行了分析。通过分析认为:目前样机驾驶室内噪声较大,而影响该驾驶室内噪声的主要声源是排气噪声、机体噪声、主阀噪声和驾驶室自身辐射的噪声,驾驶室本身的声学特性不理想是影响其内部噪声的另一个重要原因,在分析的基础上,提出了有效降低该驾驶室内噪声的措施。
Based on a large number of tests,the noise sources of a wheeled loader cab are determined and the acoustic characteristic of the cab is analyzed.The conclusion is that the main noise sources which dominant the noise in the cab are exhaust noise,engine body noise,main valve noise and the noise radiated from the walls of the cab itself;and that the acoustic characteristic of the cab is unfavorable for the reduce of noise in the cab is another important factor to cause the noise remain high.Some methods to control the cab noise are suggested after tests and analysis.
