摘要 提出了一種遠(yuǎn)場(chǎng)水下爆炸作用下艦船設(shè)備沖擊響應(yīng)一體化動(dòng)力學(xué)模型。該模型將動(dòng)態(tài)設(shè)計(jì)分析方法(DDAM)與Taylor平板理論相結(jié)合，，使得對(duì)艦船設(shè)備沖擊響應(yīng)分析更為高效。將船體外殼看做平板，將船體各層甲板和設(shè)備看做附加在平板上的多個(gè)質(zhì)量，將水下爆炸沖擊波看做指數(shù)衰減波，形成了一維分析模型。能夠根據(jù)水下爆炸當(dāng)量、爆距、艦艇噸位、總尺度、結(jié)構(gòu)和設(shè)備質(zhì)量與支撐剛度等參數(shù)預(yù)測(cè)艦船與設(shè)備的沖擊響應(yīng)。預(yù)測(cè)結(jié)果與艦船縮比模型水下爆炸試驗(yàn)結(jié)果進(jìn)行了對(duì)比。從總體上看，船體沖擊響應(yīng)譜的趨勢(shì)和量級(jí)一致。
