聚能战斗部侵彻水介质装甲仿真试验

Simulation Test of Shaped Charge Warhead on Penetration Water Medium Armor

为了提高现代潜艇的抗毁伤能力,使用LS-DYNA软件的多物质ALE算法对鱼雷聚能战斗部侵彻水介质装甲进行了仿真试验分析。从鱼雷的毁伤机理出发,定义了材料模型和状态方程,给出了侵彻体头部传播路径上节点的最大速度拟合曲线,并解决了仿真试验中经常出现的计算不稳定问题。仿真结果表明,所设计的战斗部满足考核要求,可为聚能战斗部毁伤威力评估和潜艇模拟靶设计提供参考。

In order to improve the anti-damage capability of the modern submarines, this paper used multi-material ALE algorithm of LS-DYNA software to conduct the simulation test analysis of shaped charge warhead penetrating water medium armor. Based on damage mechanism of the torpedo, material models and equations of state （EOS） were defined. And then the fitting curve of the maximum node velocity on the propagation path of the penetration head was given. The problem of computing instability often appearing in simulation test also was solved. The simulation results showed that the designed warhead can meet check request, and can afford reference for the evaluation of shaped charge warhead damage power and simulate targets design of submarine.
