摘要
基于NAPA软件对某甲板货船进行建模分舱,计算了船舶概率破舱后三个初始工况下所有破损组合的弯矩值,并采用VB编程语言产生最大弯矩包络曲线;对破损后船舶的弯曲剩余强度进行了确定性分析研究,分析并得出了满足许用应力时舷顶和舭部所允许的最大破损范围。概率破舱载荷计算结果较为安全可信,且弯曲剩余强度分析方法对船舶破损时强度的判断有一定的参考作用。
To make a deck cargo ship＇s model and define subdivision based on NAPA, then all the damaged conditions＇ bend value is obtained after calculating the probabilistic damage stability. The VB programming language is used to draw the maximum bending moment envelope based on those bend value. This paper researches on the bending residual strength of damaged ship by a deterministic method, then conclude the top＇s and bilge＇s maximum damaged extent when allowable stress reached. The results of load calculation based on probabilistic damage are secure and credible, at the same time, the analytic method of bending residual strength can be a kind of reference to the judgment of damaged strength.
