三体船连接桥结构波浪载荷研究

根据三体船船型简要分析连接桥结构波浪诱导的剖面载荷特征。以三维势流理论为基础,应用简单格林函数法对三体船在波浪中运动与载荷的时历进行仿真计算,并将时域结果转换为频域,之后对航行于北大西洋的三体船的连接桥波浪载荷进行长期预报,最终探索三体船连接桥纵向剖面的各载荷分布规律和趋势。

Long Term Prediction and Analysis of Wave Loads on Trimaran Cross Structure

In this paper, the wave load on the sections of trimaran induced by its cross structure was analyzed preliminarily. Based on 3-D potential fluid theory, simple Green function method was used to simulate the motion of the trimaran and loads on it in time domain. The results in time domain were transferred into frequency domain. A long-term prediction of wave loads on cross structure was made assuming the trimaran traveling on north Atlantic. Finally, the distribution and the trend of the loads on the longitu...
