摘要
以不对称多体平台为研究对象,采用三维势流理论确定该船型的波浪设计载荷,并进行随机海浪下的载荷特性分析,结合劳氏三体船规范,将规范计算值与数值预报结果进行对比,分析三体船劳氏规范在不对称多体平台上的适用性,并对超出规范适用范围的情况进行讨论和修正。
An asymmetric multi-body platform was selected as the research object.The wave loads acting upon the platform were predicted by means of three-dimensional potential flow theory.The long term response for wave loads was calculated and wave load characteristic was analyzed.Considered with the specification for trimaran by LR,the formula calculation values were compared with the numerical prediction results.The applicability of LR rules for trimaran in design of the asymmetric multi-body platform was analyzed,and the formula was revised pertinently in the condition of beyond the scope of application of the specification.
