摘　　要：运用通用有限元程序ABAQUS对水中兵器静态爆炸攻击作用下的舰艇冲击响应进行数值模拟分析,并数值模拟出舰艇关键部位的冲击响应特征,成功地解决了流-固耦合和单元失效等关键问题,数值模拟出水域流场压力、舰艇应力响应和加速度响应的结果。数值分析获得的舰艇在水中兵器静态爆炸试验工况下的响应结果与理论计算结果基本相符,具有较高可信度,为水中兵器静态爆炸试验工况的设置和舰艇抗爆结构的设计提供有力的依据。The shock response of a warship has been simulated by the general finite element program ABAQUS,the problems such as fluid-structure and element failure were effectively solved by ABAQUS when the explosion was static by underwater weapon,the results of the response were obtained. The laws of flow field pressure,stress response of the hull and the acceleration response were revealed. The calculation results which achieved from numerical analysis corresponding to theoretical analysis,and it could provide evidence for static explosion test of underwater weapon and warship structure design.
