| 摘 要： | 应用弹性波在带圆柱通道橡胶体内传播的理论，分析了穿孔橡胶体的吸声机理。针对有限厚的橡胶结构体，讨论了各等效参数及结构体的声学性能，用传递函数法把均匀圆柱通道结构推广至过渡型空腔结构的橡胶体。并通过对结构体样品的实验，证实了理论分析结果是正确的。

| Abstract: | By using the propagating theory of elastic wave the attenuation mechanisms of the elastomer with cylindrical bores is analyzed. The equivalent dynamic elastic moduli and the acoustic pro perties of the limited thickness elastic structures are discussed. Further, the even cylindrical bores structure is extended to a transitional cavity one. Finally, the validity of the theoretic analysis presented here is verified experimentally. |
