摘要
舰艇非接触水下爆炸冲击响应是一个重要而复杂的问题,对舰艇结构和设备抗爆抗冲击的研究有着重要的意义。运用有限元程序ABAQUS对舰艇在近距离非接触水下爆炸作用下的冲击响应进行了数值仿真,详细给出舰艇冲击响应的结果,由此获得舰艇结构的应力响应、加速度响应和速度响应的规律,为实船抗冲击试验奠定了理论基础。数值仿真所得舰艇响应规律与实际计算分析情况基本相符,为舰艇抗爆结构设计提供参考。
The dynamical response to underwater explosion of a warship is an important and complex problem, which has great importance to the research of ship structure and equipment anti-explosion. In this paper, the dynamical response of a warship has been simulated by the commercial finite element program ABAQUS, and the results of the shock response for the ship is shown in detail thus, the stress response of the hull, the acceleration response of the hull and the speed response of the hull are obtained, which establish the theoretical basis for impact test of real ship. The response regularity of numerical simulation are corresponding to actual computing analysis, which provides a strong basis for ship structure design.
