摘要
基于势流理论和格林函数,探索五体船在不规则波中运动的波浪载荷响应函数,并且运用波谱分析法,采用北大西洋波浪散布图,对船体的几个典型剖面作波浪载荷的长期预报。分析不同航速、不同浪向角下典型剖面上的弯矩和剪力,研究五体船在波浪中运动时剖面载荷的分布规律。
According to the characteristics of pentamaran,the wave load response function of pentamaran traveling in irregular wave was calculated based on potential flow theory and Green＇s function.The long term prediction of wave loads of typical sections of the ship sailing in North Atlantic were performed by spectral analysis.The bending moment and shearing force of typical sections were analyzed with different speeds and headings,the distributions of wave loads of different sections were obtained.
