摘要/Abstract

摘要： 由于三体船片体与主体的相互干扰，不同片体布局将对三体船受到的波浪载荷产生显著的影响.利用比二维切片理论更加合适的三维势流理论，并结合格林函数法，求得在不同航速、浪向角以及不同的片体纵横向布局时特定船体剖面上的波浪载荷响应，包括波浪垂向弯矩和剪力.用波谱分析法对计算结果进行比较，得到了三体船在不同航速、不同片体布局下波浪载荷的分布规律，以及三体船所受波浪载荷较小的片体布局.

Abstract: Because of the interaction between the main hull and the outrigger hulls the wave loads will be quite different by different arrangement. Based on the threedimensional potential theory and Green’s function, the wave loads, including vertical shear force end vertical bending moment at different locations on the main hull with respect to different staggers and clearances, were derived by the spectral analysis. Several ship speeds and wave headings were also considered. A suitable arrangement was got by comparison.

Key words: trimaran, three-dimensional potential theory, optimum of outrigger hull, wave loads
