【摘要】:国际海事组织已基本确定了完整船瘫船状态下的第2层薄弱性倾覆概率评估方法。由于破损舰船在风浪中运动的复杂性,破损舰船瘫船状态下的倾覆概率评估方法还未提出。基于完整船瘫船失效模式评估方法的思想,对破损舰船的横摇运动进行简化,提出一种评价破损舰船瘫船状态下倾覆概率的方法,并利用实船进行计算分析。分析各参数对倾覆概率的影响,研究对称进水和非对称进水这2种情况下的倾覆概率。结果表明:所提的用于评价破损舰船瘫船状态下倾覆概率的方法可行,其中非对称进水更为危险,可为研究破损舰船瘫船稳性提供参考。
[Abstract]:The IMO has basically determined the probability evaluation method of the second layer weakness overturning under the condition of complete ship paralysis. Because of the complexity of the damaged ship moving in the wind and waves. The evaluation method of capsizing probability under the condition of paralyzed ship has not been put forward. Based on the idea of the evaluation method of failure mode of the intact ship, the rolling motion of damaged ship is simplified. This paper presents a method to evaluate the capsizing probability of a damaged ship under the condition of paralysis, and analyzes the effect of each parameter on the capsizing probability by means of the calculation and analysis of the real ship. The overturning probabilities of symmetric and asymmetric influent are studied. The results show that the proposed method is feasible to evaluate the overturn probability of damaged ship in paralyzed state, and asymmetric influent is more dangerous. It can provide a reference for studying the stability of damaged ship paralyzed ship.

【正文快照】: 0引言船舶稳性规范是船舶设计的指导性文件。第1代完整稳性规则,即《2008年国际完整稳性规则》(2008 IS Code)[1-2]现已开始执行,但该规则主要是基于经验,不足以防止因动态稳性而导致的舰船倾覆的发生[3]。因此,国际海事组织(IMO)启动了第2代完整稳性衡准的制定工作。完整舰船,
