摘　　要：介绍了进气系统噪声产生的机理及其影响因素,对某开发中车型存在的问题进行研究,通过频谱分析、噪声源识别判定抱怨噪声由进气系统引起,针对抱怨提出了两种解决方案。文章不仅在理论计算、仿真分析方面给出了解决进气噪声的方法,而且通过试验验证了理论计算和仿真分析的有效性。The theory and effect factors for intake system noise are introduced, and one case is introduced. One developing vehicle is complained, by the frequency analysis and noise source discernment it is found that the complaint noise comes from intake system. The countermeasure is given not only through the theory and simulation calculation, but also through test to prove the theory and simulation is effective.
