摘要/Abstract

摘要： 针对减摇鳍加强结构设计难度大和载荷复杂的特点，提出一种CAD/CAE一体化设计和分析方法.对减摇鳍加强结构进行三维结构设计、水动力分析和结构性能评估.其中，采用多点约束法实现模拟减摇鳍加强结构与鳍座的2种非协调性单元之间的载荷传递，应用自由面格林函数法和三维线性势流理论求解船体运动响应和水动压力.通过研究关键技术，为减摇鳍加强结构设计和分析提供新的技术途径.

Abstract: According to the complicated characteristic of the ship fin stabilizer reinforced structural design and loads, a CAD/CAE integrated design and analysis method was presented to do three-dimensional structure design, hydro-dynamic analysis and structure property assessment of fin stabilizer reinforced structure. In this research, the multi-point constraint method is adopted to realize the load transfer between two kinds of discordant elements, which simulate fin stabilizer reinforced structure and fin stabilizer foundation, the ship motion response and hydrodynamic pressure are obtained by the free surface Green function method and the three dimensional linear potential flow theory. The key techniques discussed in this research provide a new technical approach for fin stabilizer reinforced structural design and analysis.

Key words: fin stabilizer, multi-point constraint method, dummy element, CAD/CAE integration, potential theory
