集装箱船波浪载荷的研究

Research on the Wave Loads of Container Ship

通过船舶三维运动程序进行了船舶运动与波浪载荷的初步分析.以一艘5 500 TEU集装箱实船为例,通过设置不同航行条件来确定与运动和载荷最大值对应的航向角,得到了单位规则波作用下的运动振幅以及各种航向角下中剖面的受力转换函数和受力转换频谱,得到了主要载荷参数最大值所在位置、数值以及相应的航行条件,最后运用波谱理论进行了长期波浪载荷分析,并与现行规范进行了比较.该结论可用于集装箱船极限载荷分析,也可为船体结构设计提供参考.

In this article ship motions and wave loads were analyzed by using three dimensional motion of the ship program. As an example of a 5500 TEU container ship,the heading angles of maximum motions and loads,amplitude of movement under the action of unit regular wave,load conversion functions,conditions and RAO（ Response Amplitude Operator） of middle section at different angles had been determined. The maximum dominant load parameters were also obtained. At the end the long-term wave loads were calculated through the spectrum theory,and the results were compared with the values of classification rules. The conclusions can be used to analyze ultimate loads of the container ships,and can also be the reference for ship structural design.
