摘要 提出了一種遠場水下爆炸作用下艦船設(shè)備沖擊響應一體化動力學模型。該模型將動態(tài)設(shè)計分析方法(DDAM)與Taylor平板理論相結(jié)合，，使得對艦船設(shè)備沖擊響應分析更為高效。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)預測艦船與設(shè)備的沖擊響應。預測結(jié)果與艦船縮比模型水下爆炸試驗結(jié)果進行了對比。從總體上看，船體沖擊響應譜的趨勢和量級一致。
