摘要
在计算船舶的破舱浮态时,常存在一些极端情况以至于迭代计算过程无法正常收敛求解。为了在计算中预先判断浮态方程是否有解,基于船舶倾覆的原理,预估了破舱浮态方程的有解范围,以及船舶可以承受的最大损失浮力,对求解浮态方程的迭代方法及其计算模型有参考价值。
The iteration sometimes does not converge when we solve the floating condition equation after the ship is damaged. Based on the theory of capsizing, a method to define whether the solution of the equation exists is introduced, and the method can give the range of the solu- tion and the most loss of buoyancy a ship can withstand before the iterated calculation, thus a new reference for the model of calculation of the floating condition is provided.
