| 摘 要： | 采用两种方法（一是利用WALCS软件，基于三维频域线性水动力理论；二是利用3小时波浪弯矩有义值MS，根据极值I型理论）进行船舶波浪弯矩短期预报，并分别计算得到16艘船舶（6艘散货船、10艘油船）的短期波浪弯矩。经比较发现，根据极值I型理论得到的短期波浪弯矩与WALCS软件短期波浪弯矩偏差较小，在工程实践中具有一定参考价值。

| Abstract: | This paper predicts ship wave bending moment in a short-term by two methods：one is based on the 3D linear hydrodynamic theory by WALCS, and the other is based on the extreme value theory of type I by using the wave bending moment defined values MS during three hours. It separately calculates the short-term wave bending moments of sixteen vessels （six bulk carriers, ten tankers）. It finds out that the short-term wave bending moments obtained by the extreme value theory of type I have a smaller deviation with results of WALCS, which could provide certain reference in engineering practice. |
