Numerical analysis of acoustic characters in near field and self-noise of ship

  • 摘要: 采用结构有限元软件NASTRAN和声学边界元软件SYSNOISE,对某型艇振动与声学特性数值计算问题进行了研究。通过基于全船三维有限元分析模型的频响分析计算,获得该船结构振动响应特性参数。以振动频响分析计算结果作为声学边界条件,考虑球面点噪声源的影响,建立了全船三维边界元声学分析模型;并采用间接边界元法,对某型艇近场和自噪声声学特性进行了计算。所得计算结果与该船实测数据进行了对比,证明本文计算方法是可行的。
    Abstract: Numerical analysis of acoustic characters in near field and self-noise of ship is studied by using structural FEM software NASTRAN and acoustic BEM software SYSNOISE. First, the vibration response characters are computed based on the 3-D FE model of ship, then taken the vibration characters of the ship as boundary conditions, a 3-D acoustic BE model is constructed and the influence of point sound source is also taken into account. At last the acoustic characters of the ship in near field are calculated by using indirect BEM. The computed results are compared with the experimental results, and it shows the effectiveness of the proposed method.
