微小型仿生鱼破甲战斗部结构设计与毁伤威力分析

微小型仿生鱼破甲战斗部结构设计与威力仿真分析摘要：在现代化战争中中，水下微小仿生鱼群的特点是个体体积小、功耗低、成本低。本文设计了一种基于仿生鱼形结构的聚焦战斗机，以提高对水下潜艇目标的拦截和破坏能力。在静水压力条件下，在距离目标板0、10、20mm的位置，用于由不同多边形电荷（多边形射流、多边形棒射流、爆炸性投影仪）形成的不同穿透器的不同穿透过程，以及多边形射流在水下5、10、15m处穿透到水介质中，在AUTODYN中进行了数值模拟和损伤分析。结果发现：随着水深的增加，射流似乎积聚得更大，能量在空气中缓慢，在水中迅速衰变，爆炸位置越深，离靶板越远，对靶板的穿透作用越弱。关键词：微小型仿生鱼破甲战斗部：装药结构：毁伤威力分析：数值仿真Structure Design and power simulation analysis of mini-bionicfish armor-piercing warheadAbstractIn intelligent warfare,underwater tiny bionic fish have thecharacteristics of small individual size,low power consumption andlow cost,and this paper designs a concentrated energy warheadbased on the shape and structure of bionic fish to improve theinterception and damage of underwater submarine targets.Under thecondition of hydrostatic pressure,AUTODYN was used to numericalsimulation and analysis of the penetration process of different shapedenergy penetrating bodies (shaped energy jet,shaped rod jet,explosion shaped projectile)formed by different shaped chargestructures at a distance of 0,10 and 20mm from the target plate and 5,10 and 15m underwater by the shaped energy jet.The results showedthat the jet would have obvious accumulation with the increase ofwater depth.The kinetic energy weakens according to linear law in airand exponentially in liquid medium;The deeper the explosionlocation,the farther away from the target plate,and the weaker thepenetration effect on the target plate.Key words:micro-small bionic fish armor-breaking warhead,Chargestructure,Destruction power analysis,Numerical simulation目录1绪论..11.1研究背景11.2国内外研究概况…1.2.1聚能射流破甲理论研究.21.2.2试验方法和试验测量方法1.2.3聚能战斗部水下特性研究.0.31.3设计内容与方法2仿生鱼战斗部结构设计与目标靶确定…52.1微小型仿生鱼破甲战斗部设计.................................2.1.1仿生鱼外形设计.52.1.2微小型仿生鱼破甲战斗部结构参数2.2潜艇典型结构与目标靶参数.….83微小型破甲战斗部水中对目标靶毁伤的数值仿真93.1微小型破甲战斗部水中对目标靶毁伤模型建立93.1.1仿真模型.93.1.2有限元模型.113.2不同微小型破甲战斗部水下距靶板不同距离对单层靶的毁伤效果分析…123.2.1聚能射流水下距靶板不同距离对单层靶的毁伤效果…123.2.2聚能杆式射流水下距靶板不同距离对单层靶的毁伤效果.…203.2.3爆炸成型弹丸水下距靶板不同距离对单层靶的毁伤效果283.2.4仿真结果对比分析..363.3聚能射流不同爆炸水深对单层靶的毁伤效果分析363.3.1聚能射流不同爆炸水深对单层靶的毁伤效果.36
