本文的目的是研究浮体的自由度（DOF）是否对甲板上绿水的最大冲击压力有显著影响。采用实验和数值模拟的方法，对带有甲板室的箱形浮式结构进行了绿水荷载分析。甲板上的绿水和对甲板室的冲击是由聚焦波群撞击浮式结构体产生的。计算采用基于二维约束插值剖面的模型，求解具有自由表面边界条件的Navier-Stokes （N-S）方程来处理非线性水-结构相互作用。采用流体体积（VOF）型双曲线切线捕获自由表面进行界面捕获/斜率加权（THINC/SW），比原THINC方案精度更高。通过一系列模型与模型之间的比较，在二维玻璃壁波浪槽中进行了仿真验证。在不同的落差情况下，实验水面高程、体运动和冲击压力与计算结果比较满意。结果表明，随着自由度的增大，绿水冲击压力峰值迅速减小。
The aim of the present work is to investigate whether the degree of freedom (DOF) of a floating body has a notable effect on the maximum impact pressure due to green water on deck. The analysis is carried out for a box-shaped floating structure with a deckhouse, using experimental and numerical means to model the green water load. Green water on deck and impact on the deckhouse is generated by the impingement of a focusing wave group on a floating structure. Computations are performed using a two-dimensional constrained interpolation profile-based model solving the Navier–Stokes (N–S) equations with free surface boundary condition to deal with nonlinear water–structure interactions. The free surface is captured by a volume of fluid (VOF)-type tangent of hyperbola for interface capturing/slope weighting (THINC/SW), which is more accurate than the original THINC scheme. The verifications of the simulation through a series of model-to-model comparisons are performed in a two-dimensional glass-wall wave tank. Experimental water surface elevations, body motions and impact pressure are compared satisfactorily with the computed results for different DOFs cases. As a result, the peak impact pressure due to green water decreases rapidly with the increasing DOF.
