耗散系数修正对波浪载荷预报的影响研究

在参考模型试验结果选取适当月池自由面耗散系数的基础上,对目标船进行波浪载荷预报。选取合理的月池自由面耗散系数,以准确模拟月池围壁压力;进而准确计算月池开孔对船体梁波浪载荷的影响,形成一套数值计算与模型试验相结合的带月池船体梁波浪载荷预报方法。研究成果为船舶波浪载荷预报提供参考。

Influence of dissipation coefficient correction on wave loads prediction

The wave induced loads of the target ship are predicted based on the selection of the appropriate dissipation coefficients in the free surface of the moon pool which refer to the model test results. The proper dissipation coefficients are selected to simulate the pressures around the wall of the moon pool exactly, and then to calculate the influence of the moon pool opening on the wave loads on the hull girder. It finally forms a method to predict the wave induced loads on the hull girder by the combination of numerical calculation and model test, which can provide reference for the wave induced loads prediction.
