电解多孔铁镍薄板结构的吸声性能
Keywords: 材料科学基础学科,吸声,多孔金属,微穿孔,吸声材料
Abstract:
？对具有不同参数的单层电解多孔铁镍薄板结构及双层复合结构的吸声特性进行了试验和分析.将电解多孔铁镍薄板理想化为超细微孔结构,采用平均孔距和平均孔径利用微穿孔理论计算了电解多孔铁镍薄板结构的吸声性能,并与实测值进行了比较.结果表明,单层空腔电解多孔铁镍薄板结构具有很强的共振吸声特性和良好的吸声性能,吸声系数大于0.6的频带超过2个倍频程.双层复合结构可明显拓宽吸声频带,进一步提高吸声性能.对于单层电解多孔铁镍薄板结构,采用平均孔径和平均孔距根据微穿孔理论获得的吸声系数计算值与实测值吻合得良好;对于双层复合结构,吸声系数计算值与实测值的频率特性相近,最大值接近,但存在一定的频率偏移.
