【摘要】 对船舶，特别是超规范船舶，进行结构的直接计算设计时，首先要知道波浪弯矩设计值。 要确切地做到这一点，设计人员应合理地选择船舶航行海域的海浪长期统计资料，然后根据船 舶的装载工况和实际可能达到的航速，借用线性理论或非线性理论进行波浪弯矩的长期预报 来确定设计值。本文就一艘大型集装箱船舶，按五个典型海域的海浪统计资料，对波浪弯矩及 波浪合成弯矩作了长期预报计算，并与 ＩＡＣＳ的统一纵强度要求ＵＲ—Ｓ１１的结果作了比较和 分析，给出了对船舶结构直接计算设计有指导意义的几点结论。更多还原

【Abstract】 First of all the design values of wave-induced bending moments must be estimated, when the direct structural design method is used for general ships designing, especially for ships beyond rules. In order to do so, designers must well recognize and rationally select the wave data of sailing areas, in which the ship will execute its mission. Then according to the loading conditions and enabling velocities, with linear or non--linear strip theory and codes, the long-term predictions of wave bending moments are carried out to determine the design values. In this paper, five sets of wave data from different sources are analyzed. Based on the scatter diagrams of these wave data, the long-term wave bending moments, including wave-induced and slamming responses, are predicted for a large container ship. The results are analyzed and compared with IACS-S11. Finally, some suggestions are made for direct design calculation of wave loads on ships.更多还原
