摘要
作为海上战争的主要平台,舰船目标时刻面临多样化威胁,其中水下爆炸无疑是最具破坏力的一种.为深入了解水下爆炸作用下舰船结构毁伤和动响应特征,建立阿利伯克级驱逐舰简化模型,利用非线性有限元软件开展全舰结构水下爆炸数值仿真计算,分析不同爆炸距离下舰船毁伤破坏过程以及重点位置过载加速度特性.研究结果表明,近场水下爆炸作用下舰船破坏形式以局部大破口为主,远场水下爆炸对舰船的破坏以整体的鞭状运动为主.
Abstract
As the main platforms in maritime warfare,the warfare ships face various threats,among which underwater explosion is the most destructive one.In order to study the structural damage and dynamic response characteristics of ship under underwater explosion,a simplified model of Arleigh Bruke-class destroyer is established,and the underwater explosion is numerically simulated using nonlinear finite element software.The process of ship damage at different explosion distances and the overload acceleration at key locations are analyzed.The results show that the large local damage fracture of ship is the main damage form of near-field underwater explosion,and the whole whiplash movement of ship is the main damage form of far-field underwater explosion.
