金属橡胶是一种由金属丝制成的新型材料,具有良好的环境适应性与制造工艺性,在振动与噪声抑制方面有着广阔的应用前景。本文基于刚性骨架多孔材料内流吸声Johnson-Allard模型,对金属橡胶进行了吸声性能理论推导,得到了金属橡胶的可设计参数——材料参数(孔隙率、丝径)、结构参数(厚度、空腔深度)与吸声性能的关系,通过数值计算讨论了材料参数、结构参数对吸声性能的影响规律。本文研究为金属橡胶用于吸声设计奠定了基础。 Metal rubber is a new type of material made of metal wire, has good environmental adaptability and manufacturing process, and has broad application prospects in vibration and noise suppression. Based on the Johnson-Allard model of infiltration of rigid skeleton porous materials, the acoustic properties of metal rubber were deduced. The design parameters of metal rubber - material parameters (porosity, diameter), structural parameters (thickness , Cavity depth) and sound-absorbing performance, the effects of material parameters and structural parameters on sound-absorbing performance were discussed through numerical calculation. The research in this paper lays the foundation for the metal rubber to be used in sound absorption design.
