摘要
采用表面元法计算船舶的稳性 .这种方法是把船舶的表面分解成许多小的表面单元 ,然后计算在某一倾角下每个小单元所承受的静压力 ,对静压力进行积分就可得到浮力的大小、方向和作用线 ,从而算出某倾角下的回复力矩 .对实船的稳性计算结果表明 ,无论是破损船 ,还是未破损船 。
This paper presents the mathematical formulation of surface element method to evaluate the stability of vessels. The technique depends on descriping the surface of the vessel in terms of many small finite elements, determining the hydrostatic pressure on each element for a heel angle,and integrating the pressure forces to find the magnitude, direction, and line of action of the buoyant force. This will result in the righting moment for a heel angle.The results for some vessels prove that this method is suitable for calculation of the intact vessel and damaged vessel stability curves.
