摘要
基于三维势流理论和简单格林函数法,探索了三体船在规则波中运动的频响函数,并对航行于北大西洋海域的全船典型剖面波浪载荷进行了长期预报,分析了不同浪向角时典型剖面的剪力、弯矩和扭矩极值,研究了三体船剖面载荷的分布规律和趋势,为三体船结构设计提供了一定的依据。
Based on the 3-D potential fluid theory and simple Green function method, the frequency response function of trimaran in a regular wave was explored and the long term predication of the wave loads of typical section of the whole ship voyaging on the North Atlantic was performed. The max values of shearing force, bending moment and torsion moment for a typical section were compu- ted when the trimaran was on different heading angles. Therefore, the distributions of these section loads are obtained. The results provide a foundation for the design of trimaran structures.
