摘　　要：应用国际上通用的有限元程序ABAQUS中的声固耦合算法模拟分析了舰船受爆炸载荷作用的整个过程,包括冲击波载荷作用和气泡脉动引起的脉动载荷作用.通过大量的数值模拟计算,分析和总结了药包在舰船附近以不同位置、不同深度、不同装药量爆炸时气泡脉动载荷对船体总纵强度的影响,得出了一些有规律性的曲线,并校核了典型工况下气泡脉动载荷以及气泡脉动载荷和波浪载荷联合作用下船体的总纵强度.计算结果表明:校核船体在气泡脉动载荷作用下的总纵强度的同时必须计入波浪载荷的影响,该结果对相关理论研究和工程计算具有一定参考价值.The whole process of warship subjected to underwater explosion, including the shock wave and pulse load coming from bubble pulse was simulated and analysed using the coupled acoustic-structural algorithm in FEM software-ABAQUS. Through plenty of numerical simulations, the effects of ammunition packages with varied positions, varied depth and varied charge on warship＇s overall longitudinal strength were analyzed and summarized. Some curves reflecting the rules of these effects were obtained. The overall longitudinal strength was checked when the warship was subjected to the bubble pulse load and the combined action of bubble pulse and wave loads in several typical situations. The calculating results indicate that the wave loads effect must be considered when checking the overall longitudinal strength of the warship subjected to the bubble pulse loads, which offers a valuable reference to similar theoretical research and engineering.
