Theoretical analysis on sound absorption characteristics of metal rubber

School of Jet Propulsion, Beijing University of Aeronautics and Astronautics, Beijing 100191, China

摘要

摘要: 对金属橡胶材料的吸声特性进行了理论研究.针对金属橡胶多孔性的特点,以瑞利模型为基础,根据圆管中声传播理论和亥姆霍兹共鸣器原理,建立了金属橡胶的吸声理论模型,推导出金属橡胶吸声系数的计算公式.并通过阻抗管法对不同结构参数的金属橡胶试验件进行了吸声性能的试验.试验结果验证了该理论模型的准确性.该吸声模型为金属橡胶在吸声降噪方面的工程应用提供了理论依据.

Abstract: The theoretical research on sound absorption characteristic of metal rubber (MR) was performed. On the basis of Rayleigh model and according to the sound propagation theory in pipe and the principle of Helmholtz, the acoustic model of MR was established, and formula of absorption coefficient was derived. With the acoustic impedance pipe, the experiments for noise reduction characteristic of MR with different structural parameters were carried. The results of the test show the accuracy of this acoustic model. It provides theoretical support for the further engineering application of MR in the field of noise reduction.
