| 摘 要： | 以一艘典型的非常规主尺度比的油驳为研究对象,采用直接计算法进行波浪载荷计算,并与传统经验公式法的计算结果进行比较。计算结果表明:前者与后者的波浪弯矩比值约1.4,波浪剪力比值约1.5。大量计算实践也表明直接计算值普遍大于规范计算值。因此,对于非常规主尺度比的船舶而言,对波浪载荷进行直接计算是必要的。

| Abstract: | Taking a typical oil barge with unusual ratio of main dimension as the research object,the wave load calculation is carried out by direct calculation method and the results obtained are compared to the traditional empirical formula method.The calculation results show that the ratio of wave bending moments of former to later is about 1.4,and the ratio of wave shearing force of former to later is about 1.5.A large number of calculations indicate that the direct calculation results are bigger than formula method results.It's necessary to calculate the wave load using direct calculation method for the ships with unusual ratio of main dimension. |
