摘要
在波浪载荷的非线性直接计算和实船缩比模型试验中,阻尼在船体波浪高频载荷成分随时间的变化中起着重要的作用。试验模型的阻尼系数与实船的差异,直接影响到模型试验能否准确反映实船的载荷特征。论文针对船体阻尼的影响进行分析,并进行不同阻尼下实船波浪弯矩载荷的直接计算和缩比模型试验的比较,探讨阻尼对船体波浪弯矩的影响,并推荐与目标船类似船型的阻尼系数的选取方法。
Damping has a significant effect on high frequency load components of a hull in nonlinear direct calculation of wave loads and ship model tests.Difference of hull damping coefficient between the actual ship and its model determines whether the model test reflects the load characteristics of the actual ship accurately.Theoretical analysis,direct calculation and model test are reviewed,and influence of damping on the wave bending moment is analyzed.A method is recommended to select damping coefficient for type of ships similar to this target one.
