锚泊船在波浪中的下沉量研究

Sinkage of anchored vessels in waves

运用基于流体力学三维势流理论的SESAM软件,分别对不同排水量的集装箱船、油船、散货船样本在不同有义波高及水深情况下的下沉量进行计算分析,得出其垂向运动的吃水倍率随船舶排水量的变化曲线,从而统计出锚泊船在波浪中下沉量与吃水的数学关系.

The sinkage of selected five different displacement of container ships,tankers and bulk carriers in different waves and depth are respectively calculated by using SESAM software based on three-dimensional potential flow theory of ship hydrodynamics,and the curves of which the draft rate of the ship＇s vertical motion changed with displacement are obtained.And then the mathematical relationship between the sinkage of anchored vessels in waves and the ship＇s draft is summarized.
