摘要
分析组成水下翼型的板壳体的力学特性,内容包括板壳的力学分析方法,对满足工程精度的一阶剪切变形理论进行了讨论,综述了水下壳体结构—流体耦合的声学特性和水下壳体的数值研究方法;同时综述水下翼型,主要是船舶中不同翼型结构的水动力研究,着重讨论了流体通过二维振动翼型的声辐射研究,并对水下翼型的水洞实验给出了主要的实验结果。
This paper presents in details the mechanical characteristics of the shell structure, which composes the underwater aerofoil. The analytical methods for shells are described. The first-order shear deformation theory, which satisfied the engineering accuracy standard, is discussed. The acoustic characteristics of the fluid shell structure interaction and the corresponding numerical methods are summarized. Also, different aerofoil structures of the ship about underwater aerofoil are reviewed with emphasis on the sound generation by flow induced vibrated aerofoil in two dimensions. The major results of the test about the underwater aerofoil in water tunnel are presented.
