共振吸声结构在汽车降噪中的应用

The Application of Resonance Sound-Absorbing Structures in Lowing Noise of Automobiles

通过理论推导分别得出薄板共振吸声结构与穿孔板共振吸声结构的共振频率,结合实验来确定胶合 板共振吸声结构的吸声性能,为其在汽车上的合理应用提供一定的科学依据。

The resonance frequencies of the sheet resonance sound-absorbing structure and the punched sheet resonance sound-absorbing structure are derived by theoretical derivations, the play-wood's structure sound-absorbing function is detemined by experiments and derivations, the scientific basis can be provided in the reasonable application of automobiles by doing so.
