眾所周知,深V船型具有高航速和良好的耐波性能。在過(guò)去的十年中,深V船型吸引起了美國(guó),英國(guó),中國(guó)等諸多國(guó)家對(duì)其的研究�，F(xiàn)在,世界上許多國(guó)家都剛剛開(kāi)始發(fā)展建造深V船型的軍艦。一些專家指出深V船型單體艦艇將是未來(lái)發(fā)展的主流。在這樣的背景情況下,對(duì)深V船型設(shè)計(jì)的研究開(kāi)發(fā)對(duì)未來(lái)海軍艦艇的發(fā)展是至關(guān)重要的。深V船型艦船的耐波性與其主尺度,V形斜升角,折角線高度相關(guān)。本研究的目標(biāo)是對(duì)4000至5000噸的深V船型驅(qū)逐艦船體外形結(jié)構(gòu)進(jìn)行概念設(shè)計(jì),進(jìn)一步分析影響穩(wěn)性,阻力和耐波性能數(shù)值結(jié)果的主因素。最后,提出優(yōu)化方案,給出修改和優(yōu)化后的驅(qū)逐艦船型。 船型幾何參數(shù)對(duì)決定船體耐波性能的好壞有著重要作用。設(shè)計(jì)師的問(wèn)題之一是選擇哪些參數(shù)需要改變且參數(shù)改變多少才能達(dá)到最好的效果。往往一個(gè)參數(shù)的變化也會(huì)影響到其他參數(shù)。因此,本文給出的方案描述了在初步設(shè)計(jì)階段,如何修改船型從而得到高耐波性能的船型的方法。為了確定船體參數(shù)和耐波性能之間的關(guān)系,通過(guò)改變折角線和修改其他的變量來(lái)系統(tǒng)的分析深V船型。使用MAXSURF計(jì)算機(jī)軟件對(duì)船體進(jìn)行了修改和耐波性能的計(jì)算。使用垂直加速度,橫向加速度,橫搖和縱搖標(biāo)準(zhǔn)對(duì)變量進(jìn)行了評(píng)估。通過(guò)...
