| 摘 要： | 根据舰船声场的特性,将舰船水下声场简化为一特殊的半自由空间声辐射问题,利用边界元法(BEM)建立了舰船水下声场的数值计算模型。通过对声场边界条件的计算机仿真和计算,获得了部分计算结果。结果表明:由所建模型计算的舰船辐射声场与真实海域中的实测规律基本吻合,该文提出的方法是有效可行的。最后对存在的问题进行了讨论。

| Abstract: | In the light of the ship acoustic field characteristics,the under-water acoustic field of the ship is regarded as a special case of the half-space radiation problems.A numerical calculation model of the ship under-water acoustic field is set up by using the boundary element method(BEM).The boundary conditions of the field are simulated by a computer.Parts of computed results are given which accord with the experimental results in the sea and support the method in this paper. |
