摘要：

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. © 2024 China Ordnance Industry Corporation.
