摘要
排气噪声是摩托车最主要噪声源之一,对某125摩托车进行了整车噪声评价和声源识别、对其不带消声器而带空管的发动机排气噪声进行了频谱分析并对消声器消声性能做过改进试验和分析计算,结果表明,该摩托车主要噪声源仍为排气噪声;改进后消声器的消声效果优于原消声器消声效果。
Various tests, analyses and calculations on complete motorcycle without muffler show that the exhaust noise ranks the first within all the noise sources. Silencing effects of the improved muffler are much better than that of the original one.
