汽车排气噪声控制的发展动向

介绍了国内外消声器设计的现状、发展趋势;指出了在进行消声器设计、试验研究中应亟待解决的问题;论述了结构优化、电控技术等在消声器结构设计上的应用。这些方面,充分展现了汽车排气噪声控制的前景。

This paper presents the current situation and evolution frends in automotive muffler design domestic and abroad, and indicates problems urgently needed to be solved in design and experimental investigation of muffler. Main points discussed are those such as optmization of muffler construction, electro—control techniques musical tone quality and application of plastics to the structural design of mufflers. Based on these descriptions the prospects in automotive exhaust noise control are revealed.
