| 摘 要： | 将流体分别视为不可压缩和可压缩两种情况建立了流固耦合方程，探讨了按可压缩流体计算水下结构振动响应对声辐射的影响．结果表明：流体可压缩性与流体边界条件、结构刚度和结构阻尼有关；在计算水下结构声辐射时，结构振动响应应当按可压缩流体计算．

| Abstract: | Two different fluid-structure coupled equations are established based on the incompressible and the compressible fluid respectively, and then the influence of the computation of the vibration responses for underwater structures based on the compressible fluid on acoustic radiation and several factors related to the influence of the fluid compressibility are studied. The results show that the influence of the fluid compressibility is related to the fluid boundary conditions, structure stiffness and structure damping. It is concluded that the vibration responses must be computed based on the compressible fluid in the computation of acoustic radiation for underwater structures. |
