摘要
涡轮增压汽油发动机所产生的高频噪声会降低车内声学品质。本文通过3D建模设计了一个多孔消声器,用于消除涡轮增压汽油机所产生的高频噪声,并利用仿真确定了高频谐振腔的布置位置,最后通过实验验证了该消声结构能够有效降低高频噪声。研究过程为解决增压发动机进气噪声问题提高了参考依据。
The high-frequency noise created by turbocharged gasoline engine lower the interior acoustics quality.A multi-hole resonator model has been created by 3D software,aiming to lower the high-frequency noise.The layout of the resonator on the air intake system has been defined through simulation.The resonator performance has been validated by experiment.Research process provides a reference to solve the high-frequency noise in a turbocharged gasoline engine.
