摘要
面对复杂的海洋环境,舰船在执行任务时,需要提升在恶劣海况下的生存能力。而舰船最可能面临水下炸弹爆炸或者风暴引起的大波浪,从而可能会发生倾覆事故。本文主要研究了舰船在发生破损情况时,如何提高其航行的稳定性,降低倾覆发生的概率。首先,本文对船体倾覆的几种模式进行分析,然后建立风浪作用模型和水下爆炸冲击波模型,并计算在上述情况下的倾覆发生概率与稳定程度。
In the face of complex marine environment, ships in the implementation of the task, the need to enhance the viability in the harsh sea conditions. And the ship is most likely to face underwater bomb explosion or storm caused by a large wave, which may occur overturned accident. This paper mainly studies how to improve the stability of navigation and reduce the probability of overturning when the ship is damaged. Firstly, several models of hull overturning are studied and analyzed. Then, the model of storm wave and the model of underwater explosion shock wave are established, and the probability of occurrence and the degree of overturning in the above cases are calculated.
