| 摘 要： | 在经典的理论框架内,对分层的复合材料壳体——多孔材料夹芯的双壁面圆柱壳体,研究自由谐和波在其中的传播.借助于一个具有同样几何特性的展开平板,评估波通过多孔夹芯层传播时大部分有效的成分.通过有效波成分的考虑,将多孔层模拟为具有等效特性的流体.因此,模型简化为一个集满流体介质的双壁面圆柱壳体.最后,评估带宽频率中结构的传播损失,并对结果加以比较.

| Abstract: | A study on free harmonic wave propagation in a double-walled cylindrical shell whose walls sandwich a layer of porous material was presented within the framework of the classic theory for laminated composite shells.The most effective component of the wave propagation through porous core was estimated by the aid of a flat panel with the same geometrical properties.Through considering the effective wave component,the porous layer was modeled as a fluid with equivalent properties.Thus,the model was simplified ... |
