摘要

为了充分发挥多孔材料背衬多孔板在中低频噪声吸收方面的优势，本研究采用Johnson—Champoux—Allard方法结合有限元模型来描述这种复合材料结构的声学特性。通过数值模拟，系统地研究了多孔板结构参数和三聚氰胺泡沫特性参数对吸声系数的影响。制备了实用的复合材料，验证了数值模拟方法的可靠性。本研究的模拟和实验数据有助于促进多孔材料多孔板结构在生活中的噪声控制设计。

Design of Melamine Foam/perforated Plates Composite Absorber for Effective Sound Absorption Performance

To give full play to the advantages of perforated plate backed by porous materials in low and medium frequency noise absorption, this study uses Johnson-Champoux-Allard method with the finite element model to describe the acoustic characteristics of this composite structure. The effects of structural parameters of perforated plate and characteristic parameters of melamine foam on sound absorption coefficient were systematically investigated by numerical simulation. Practical composite were prepared to verify the reliability of the numerical simulation method. The simulation and experimental data in this study are helpful to promote the design of porous material-perforated plate structure for noise control in life.
