泡沫铝吸声系数的量纲分析

Dimensional analysis of sound absorption coefficient of aluminum foam

量纲分析是定性与半定量分析物理问题的重要方法之一,通过对影响泡沫铝吸声性能的结构参数的分析,利用瑞利分析法对泡沫金属的吸音性能进行了研究,尝试提供一种测量和计算相结合的新方法来预测泡沫金属的吸声性能.

Dimension analysis is one of the important qualitative and semi-quantitative analysis methods to study physical problems. By analyzing the structure parameters of influence sound-ab- sorbing properties of metal foam, and using Rayleigh＇s analysis to study sound-absorbing per- formance of metal foam, we try to provide a new method which combines the measurement and caculation to predict the sound absorption performance of metal foam.
