摘要/Abstract

摘要： 为研究聚能战斗部的水下作用特性，基于光滑粒子流体动力学-有限元方法耦合算法，模拟了聚能战斗部对双层圆柱壳结构的毁伤过程。分析金属射流的形成和射流速度衰减规律，研究高速金属射流、强冲击波与气泡载荷联合作用下对双层圆柱壳结构的毁伤模式和毁伤特性，并进行了海上模型试验验证。数值模拟与试验结果吻合良好。研究表明：水中聚能战斗部对双层圆柱壳结构的破坏载荷主要有金属射流、冲击波载荷及气泡载荷3种，金属射流穿透力强，造成结构的局部小尺寸破口；冲击波载荷及气泡载荷作用面积大，引起结构的大面积破口及塑性凹陷。

Abstract: In order to investigate the underwater explosion characteristic, the damage process of shaped charge warhead to double-layer columniform shell is simulated based on SPH-FEM coupling algorithm. The formation and velocity decay rule of metal jet are analyzed. The damage modes and the characteristics of high-speed metal jet are used to study the effects of strong shock wave and bubble load on double-layer columniform shell structure. The sea model explosion tests were conducted to verify the simulation. The numerically simulated results are in good agreement with the test results. It can be concluded that the damage effects of the shaped charge warhead on double-layer columniform shell include metal jet, shock wave and bubble. The metal jet causes small crevasse on the shell, and the shock wave and bubble cause large holes and plastic hollows on the shell. Key

Key words: shapedchargewarhead, metaljet, double-layercolumniformshell, damagecharacteristic
