三体船随浪中的破舱稳性研究

Study of Damage Stability of Trimaran Hull Form in Following Waves

以一三体船型为例,研究了三体船型在波浪中的破舱稳性。对不同的破舱位置和侧体位置的多种方案进行了计算,结果表明:侧体位置不同时,最危险的破舱位置亦不同,并且破舱位置对稳性损失的影响随着侧体横向位置的增大而减小;侧体位置位于船舯时破舱稳性较好,侧体横向距离越大破舱稳性越好。

A typical trimaran as an example, the damage stability in waves is studied. Several solutions of stabilities for trimaran with different damage tank and side hull positions are calculated The result shows that the most dangerous damage tank location depends on different side hull location. Further more, the influence of the damage tank location on damage stability decreases as the horizontal position of the side hulls increases. The study also shows that when the side hull longitudinal position is near to the midship, the larger the horizontal distance of the side hull is, the better the damage stability is.
