提出了一种运用Yamada微观模型来分析压电复合材料吸声性能的方法。首先，建立了0-3型压电陶瓷/橡胶复合材料的被动吸声模型；然后，运用Yamada微观模型获得0-3型压电陶瓷/橡胶复合材料的等效参数，并将此等效参数嵌入到吸声模型；最后，对不同参数下的压电复合材料的吸声系数进行了理论计算和对比分析。结论表明：压电复合材料被动吸声时，聚合物对声能量的衰减起主要作用。

A method of analyzing acoustic performance of piezoelectric composites based on Yamada model is proposed. First,a passive acoustic model of 0-3 piezoelectric ceramic/rubber composites is established. Then,the equivalent parameters of 0-3 piezoelectric ceramic/rubber composites is obtained by Yamada model and embedded into the acoustic model. Finally,theoretical calculation and comparative analysis of the absorption coefficient of the piezoelectric composites with different parameters is carried out. Conclusions show that when piezoelectric composites passively absorb,the polymer plays a major role on the attenuation of acoustic energy.
