本文研究了蜂窝增强粘弹性层合结构的声辐射特性。分析中考虑了粘弹性材料的温度和频率相关特性，这些参数影响复合材料结构的动力学有效特性。根据齐次渐近法确定了结构的等效动刚度和动变形，得到了结构在频率场和温度场下的声辐射特性。在此基础上，研究了蜂窝结构几何尺寸对声辐射特性的影响，如远场声压和声辐射效率。最后，研究验证了退化方法与退化的数学模型，在已发表的文献中进行。
In this study, the sound radiation characteristics of the laminated structures reinforced by honeycomb and composed by viscoelastic material was investigated. Temperature- and frequency-dependent behaviors of the viscoelastic material were considered in this analysis, those parameters affected the dynamics effective properties of the composite structure. After the dynamic equivalent effective stiffness and the dynamic deformation of the structure are determined according to the homogenous asymptotic method, the sound radiation behaviors of the structures in fields of frequency and temperature are achieved. Consequently, the sound radiation characteristic, such as the sound pressure in far-field and the sound radiation efficiency that influenced by the geometry dimensions of the honeycomb structure was examined. Finally, the study is validated by the degeneration method with a degeneration mathematical model that performed in the published literature.
