进气噪声
the generation mechanism and reduction measures of engine induction noise
进气噪声产生机理分析及其降噪
In order to reduce the induction noise, an investigation was carried out towards the air-in filter acoustic performance based on experiments and boundary element calculation.
为了解决该车进气噪声的问题从而达到整车降噪的目的,应用实验与边界元法计算两种手段,对该车空滤器的频率响应特性进行了研究。
The investigation revealed that the first order of the acoustic modes of air-in filter coincides with the foundation frequency of induction noise, and that the couple in frequency domain makes the sound pressure of left side be higher than right side where exhaust system was settled.
研究发现空滤器声系统的第一阶声固有频率与进气噪声基频相耦合是造成该车辆进气侧通过噪声高于排气侧的重要原因。
