水面艦船耐波性綜合評估方法研究

發(fā)布時間:2022-11-05 17:04
  當(dāng)水面艦艇在海上航行時,耐波性是決定作戰(zhàn)能力和適用性的最重要的指標(biāo)之一。艦船的耐波性由許多特性組成:振蕩運(yùn)動,加速度,砰擊,甲板掩濕,阻力增加等,它是一個復(fù)雜的流體力學(xué)問題。因此,在船舶設(shè)計的不同階段,確定可以綜合表明具有作戰(zhàn)任務(wù)的艦船的耐波性能指標(biāo)是必要的,以用來評估設(shè)計出的艦船是否具有所需的良好的耐波性能和作戰(zhàn)適用性。 本論文分為四個方面。首先是比較深V船型和圓舭護(hù)衛(wèi)艦。從這些同等排水量(1500噸)的護(hù)衛(wèi)艦的初始穩(wěn)定性,耐波性性能和阻力來審查它們的優(yōu)勢和劣勢。使用MAXSURF軟件對這些護(hù)衛(wèi)艦進(jìn)行船體建模和研究。其次為了確定舯剖面斜升角對船體耐波性和阻力的影響,使用MAXSURF軟件設(shè)計了五艘具有相同排水量和船長的深V船型護(hù)衛(wèi)艦,舯剖面斜升角角度分別選取了210,230,250,270,29°。從船中到船尾的斜升角取為常數(shù),則船腫斜升角與中橫斜升角相等。在第三部分中,選取了具有相同船中斜升角βM=25°和不同中橫斜升角βT5°,10°,15°,20°,25°的護(hù)衛(wèi)艦來研究中橫斜升角對耐波性和阻力的影響。在第四部分中,在修改現(xiàn)有的母型船基礎(chǔ)上設(shè)計了兩艘具有相同排水量和船長的深...
