The overall strength and response of a warship subjected to underwater explosion,including the shock wave action and the pulse load action introduced by bubble pulse,was simulated and analyzed using ABAQUS finite element analysis software.Analyzed were responses of a warship under bubble dynamics load action at various depths,positions,and weights of charge,as well as when dynamite charges were blasted at different position of the warship.The regular curves,which suit the engineering application,were gained.The...

The overall strength and response of a warship subjected to underwater explosion,including the shock wave action and the pulse load action introduced by bubble pulse,was simulated and analyzed using ABAQUS finite element analysis software.Analyzed were responses of a warship under bubble dynamics load action at various depths,positions,and weights of charge,as well as when dynamite charges were blasted at different position of the warship.The regular curves,which suit the engineering application,were gained.The hull's longitudinal intensity,under typical situations and bubble impulse load action and coupled with wave loads,was checked to study the bubble impulse load action's influence on a warship's primary strength.Results indicate that the wave loads must be considered when the hull's longitudinal intensity is checked.The research has value to correlative theory research and engineering calculation.

通过数值手段研究水下爆炸气泡脉动载荷作用下的舰船船体总强度.文中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水下爆炸气泡脉动载荷作用的总体响应;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、给定深度、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,对相关理论研究和工程计算有一定参考价值.
