本文从理论上分析了平面行波入射时，在弹性圆柱壳表面覆盖一层粘弹性吸声材料时的声辐射力。辐射力函数Y-p（单位能量密度和单位横截面积的辐射力）的数值计算在很宽的频率范围内进行，特别强调涂层厚度和壳的中空空间区域的内容。可以针对各种应用仔细选择用于阻尼共振峰的各种方法，例如通过改变填充壳体的内部中空区域的流体或涂层厚度。(c)2006 Elsevier B. V.保留所有权利。
In this paper, a theoretical analysis is developed for the acoustic radiation force due to incident plane progressive waves on elastic cylindrical shells covered with a layer of viscoelastic and sound-absorbing material. Numerical calculations of the radiation force function Y-p (which is the radiation force per unit energy density and unit crosssectional surface) are performed in a wide range of frequencies with particular emphasis on the coating thickness and the content of the hollow space region of the shells. Various methods for damping resonance peaks, such as by changing the fluid that fills the interior hollow region of the shells or the coating thickness, can be carefully selected for various applications.
