基于FEM/BEM法的内部声激励水下圆柱壳声辐射计算

Sound Radiation Analysis of Submerged Cylindrical Shell Excited by Interior Point Source Based on FEM/BEM

  • 摘要: 联合有限元法和边界元法对流场中的圆柱壳点声源激励下的声辐射作了数值计算。利用有限元软件ANSYS分析了加筋圆柱壳的模态,然后将模态导入采用边界元软件SYSNOISE,计算了加筋圆柱壳结构在点源激励下的声辐射,预报了圆柱壳的内外场声压,得到了圆柱壳的声辐射功率曲线。

     

    Abstract: Numerical analysis of sound radiation from a submerged cylindrical shell excited by interior point source has been carried out by FEM/BEM. The modes of stiffened shells are calculated by ANSYS. A numerical analysis of sound radiation of stiffened shell excited by interior point source is performed by incorporating the modes into the SYSNOISE, and predictions of the sound pressure both in side and out side of the shell are made, and the curve of sound power is obtained as well.
