某微型商用车进气系统噪声优化

Light Commercial Vehicle Noise From Intake System Optimization

介绍了一款微型商用车进气系统调音的案例,通过消声室中进气口噪声测量结果,结合进气消声元件消声作用和消声原理,提出合理的进气系统结构改进方案,为进气系统设计指明方向,对进气系统的噪声控制和结构改进具有一定的指导作用。

A sample of light commercial vehicle noise from intake system optimization was introduced in this pa原per,the intake noise was test in the semi-anechoic room and study the mechanism and effective of the intake sys原tem resonator,result to optimize the structure of intake system andguide the intake system design.
