Calculation method floodability for surface ship 水面艦船不沉性計(jì)算方法
Three - compartment floodability 三艙進(jìn)水不沉性
Two - compartment floodability 兩艙進(jìn)水不沉性
Therefore , the safety of bulk carrier is widely concerned ; the theory of insubmersibility is followed by the introductions of domestic and international regulations , solutions , rules and requirements on the floodability ; introduced are the conditions of hold in flooded condition , and provided are the calculation methodology of the stability and buoyancy when flooding . the concept of cargo permeability is concretely defined , and the calculation methods of the amount of flooding waters are executed ; the application of the influence numbers simplify the calculation of the still water bending moment and shearing force in flooded conditions . a new method to calculate the maximum still water bending moment and shearing force is developed by means of the influence numbers ; the simulation system provides a means of evaluation and forecast on ship ' s danger extent after ship is damaged 在抗沉性公式的推導(dǎo)過程中采用一些假設(shè),并分析了這些假設(shè)對(duì)結(jié)果的影響;然后介紹了船舶強(qiáng)度的概念和計(jì)算方法,鑒于現(xiàn)有的剪力彎矩計(jì)算方法工作量大、效率不高的缺點(diǎn),引用影響數(shù)計(jì)算船舶進(jìn)水后的剪力和彎矩;最后根據(jù)船舶抗沉性理論對(duì)散貨船破艙進(jìn)水進(jìn)行模擬,在模擬中根據(jù)船舶破艙的實(shí)際危險(xiǎn)情況,采用直觀的圖形輸入的辦法,判斷船舶的危險(xiǎn)程度并計(jì)算船舶到達(dá)危險(xiǎn)狀態(tài)的時(shí)間以助于船長(zhǎng)做出正確快速的決策。
