| 摘 要： | 将结构有限元法和流体有限元法结合起来,根据Garlerkin法和Hamilton变分原理分别推导出离散的流体和结构的运动方程,用湿模态法求得流体附加质量矩阵,对高速船舱壁加筋板流固耦合系统进行了模态分析.并进行模态试验,研究不同水深时舱壁加筋板结构流固耦合振动模态,同时与有限元计算结果进行比较,从而揭示了该类结构流固耦合振动的动力特性,对舱壁加筋板结构的动力设计具有指导意义.

| Abstract: | In this paper, the kinetic equilibrium equations for discrete fluid and structure are derived by structural finite element method and fluid finite element method on the basis of Galerkin method and Hamilton抯 Principle. The added mass matrix for fuild is obtained by wet modal method. A modal analysis is conducted on fluid structure interaction system of bulkhead stiffened plate of high-speed ship. In order to study the modal characteristics for different depth of water, a modal experiment is done. The experimental result is compared with that of finite element analysis. The present work may offer guidelines on the dynamical design of bulkhead stiffened plate of high-speed ship. |
