Resonance radiation of elastic cylindrical shell in water

  • 摘要: 研究了在内壁简谐法向线力激励下的水中弹性圆柱壳的振动和声辐射问题,这有助于深入认识水中结构的声辐射机理,验证水下结构共振声辐射理论。本文从经典Rayleigh简正级数解出发导出共振声辐射公式,然后分别用经典公式和共振声辐射公式计算钢圆柱壳的辐射声功率及壳体表面声压曲线。计算结果表明两者符合良好。
    Abstract: Sound radiation from a submerged elastic cylindrical shell excited by internal harmonic line force is considered. It is useful for understanding the mechanisms of sound radiation from submerged structure and verifying the Resonance Radiation Theory (RRT). Firstly, the resonance radiation formula is derived from classical Rayleigh normal mode solutions, then numerical calculation for a thin steel cylindrical shell is completed by using these two methods. The results of RRT solutions are compared with that of Rayleigh series solutions, which are in good agreement.
