摘　　要：分析进气噪声产生机理及一般的控制方法,并以1款经过试验分析证明进气噪声对车外、车内噪声有贡献的SUV为例,从空滤器容积、干净空气进气管长度、脏空气进气管长度3个设计参数对进气系统进行了优化设计,并研究了这3个设计参数与进气噪声的关系。优化的进气系统取得了良好的降噪效果,同时经发动机台架验证,改进进气系统对发动机性能无影响。In this paper,the intake noise mechanism and common control methods are firstly summarized.A SUV,which is already proved intake noise contribute more on pass-by and interior noise by noise identification method,is exemplified to make intake system optimization for the pass-by and interior noise reduction.Based on 3 design parameters optimization,air filter volume,clean air duct length and dirty air duct length,and the relation between the mentioned 3 design parameters and intake noise is investigated.The outcome is that the intake noise,pass-by noise and interior noise are reduced by optimized intake system,without the penalty of engine performance.
