摘要
文章对某MPV进气系统进行优化,通过试验和分析该段噪声的特性及产生的机理,通过对空滤器出气管出气管的优化设计降低这显著噪声,改善了整车NVH性能,提高了产品竞争力。
Through experiment and analysis methods, this paper has carried out a research on a MPV's intake system noise. By optimizing the outlet pipes of the air filter, the level of noise decreased obviously. For the improvement of the MPV's NVH character increased, the competitive power of the car increased.
