流体加载下加肋板结构的声辐射特性研究
Study on the acoustic radiation characteristics of a fluid-loaded stiffened plate
  
中文摘要:
      本文采用有限元和边界元方法对加肋板结构的声辐射进行了计算分析,研究分析了加肋板结构的板厚、板面积、板边长比、肋骨惯性矩和间距、边界条件以及板材和流体介质等对结构辐射声功率的影响,得到了一些有意义的结论,从而为揭示加肋板结构声辐射规律,降低结构的声辐射提供了一定的依据。
英文摘要:
      The finite element method and the boundary element method are used to compute the structural acoustic radiation of a stiffened plate. The effects of plate thickness, plate area, ratio of length to width of plate, moment of inertia and spacing of stiffeners, boundary condition, plate material and fluid medium on radiated sound power are studied. Some conclusions of significance are made. The results obtained in this paper show the acoustic radiation characteristics of the stiffened plate and can be used to reduce its structural acoustic radiation.
