水密关闭物可靠性对生命力的影响分析

Effect of the Reliability of Watertight Closed Object on the Survivability

针对水密关闭物对生命力的影响问题,基于蒙特卡罗模拟的方式构建了抗沉性分析算法,以水密设计方案为输入,采用随机模拟的方式生成命中位置,根据经验公式确定威胁武器造成的破损半径,然后根据水密区域、命中位置以及破坏半径等确定损伤范围,开展不沉性计算确定单发命中条件下的破损稳性,采用多次模拟的方式确定舰船沉没的概率。以抗沉性分析算法为基础建立了可计入水密关闭物可靠性影响的计算模型,完成了模型的数值收敛分析。应用该模型针对不同的开口方案开展了较为系统的数值计算对比分析,确定了水密关闭物可靠性对舰船生命力的影响,进一步证明了在水线以下的主横舱壁上设置水密开口存在的技术风险,提出了设计建议。

The insubmeribility analysis method based on the Monte Carlo random simulation is constructed for the prob- lem about the effect of watertight closed ohjeet on the survivability. The watertight area design as input, the shoot position based on the random simulation, the breakage radius based on the empirical formula, the breakage range based on the water- tight area, shoot position and breakage radius are used to compute the damage stability of shoot singly. The probability of submerged of ship is computed based on lots of simulations. The computation model that can consider the effect of the relia- bility of watertight closed object based on insubmeribility analysis method is constructed. The convergence analysis is finished and the compare analysis of numerical results of different openings is got. The effect of the reliability of watertight closed ob- ject on the survivability is got, which proves that setting watertight opening on main transverse bulkhead is risky. The design advance is given.
