摘要
综合国内目前轻型汽车的排放与噪声情况，在净化与消声的研究基础上，提出用一维平面波声学理论对一种集净化、消声于一体的净化消声器的消声性能进行改进的方法——敏感度分析法，对此进行理论研究与试验验证，并在计算中，同时综合考虑净化消声器的净化性能与空气动力性能，得到性能良好的净化消声器。
Based on the onedimensional plane wave principle and the studies on of purification and noise elimination, a susceptibility analysis method was proposed to improve the noise elimination property of purification muffler. Theory analysis and experiment were carried out. In calculation, the purifying and air dynamic properties were considered. finally, a purification muffler with good property was obtained.
