摘要
结构在水下爆炸作用下会产生严重的破坏,研究水下爆炸作用下结构的响应特征和规律,并为舰船抗冲击设计提供参考。首先验证了ABAQUS软件模拟结构受水下爆炸载荷作用弹塑性响应的有效性和准确性。然后应用ABAQUS软件计算不同工况水下爆炸载荷作用下结构的动态响应。从应变、应力等角度考察了水下爆炸载荷对结构动态响应的影响。计算结果表明气泡脉动压力是结构产生鞭状响应和整体破坏的主要因素。
Underwater explosion may result in serious damages to the floating structure.The purpose of this paper is mainly to study effects of response characteristics of structures subjected to underwater explosion and provides a reference for anti-shock design of warship.The accuracy and efficiency of ABAQUS software in simulating the elastic-plastic response of structure subjected to underwater explosion were verified.The dynamic responses in terms of strain and stress of the structure under underwater explosion loading in different cases were calculated and analyzed using ABAQUS software.The calculated results show that the pressure of bubble pulse is the major factor of ship whipping and overall damage.
