| 摘 要： | 针对宽深比比较大的扁平船,研究了船舶波浪载荷长短期预报的直接计算方法。基于三维频域线性水动力理论,通过分析得出波浪载荷的响应幅算子,采用谱分析法对波浪载荷进行长短期期预报。以某试验船为例进行了计算并将结果与规范值进行了比较。得到的结论对扁平船船体强度的评估研究提供了重要参考,也为其他相关方面的研究提供了一定的借鉴价值。

| Abstract: | The direct calculation method for long/short term prediction of a flat ship wave loads is studied. Based on 3-D linear hydrodynamic theory in frequency domain, response amplitude operators of wave loads are obtained and spectrum analysis method is employed to predict the long/short term wave loads. A case study is carried out, whose results is compared with the rule calculations subsequently. The outcome could be a reference to the hull strength assessment of flat ships and other researches. |
