【摘要】 末敏弹是用现代传感器技术、光电子技术、计算机技术、信息处理技术与爆炸成型弹丸战斗部技术集成的一种攻击装甲目标顶装甲的精确打击灵巧弹药。EFP战斗部技术是末敏弹关键技术之一。 末敏弹主装药的设计,传统的方法主要是在经验的基础上依靠试验来进行。本文在分析前人工作的基础上,采用理论分析、数值模拟的手段,以成型形状和弹丸速度为指标进行战斗部的设计。首先确定关键参数:罩材、炸药种类、何种形式的药型罩、装药长径比、壁厚、曲率半径等;然后对形成的EFP进行威力分析,结果表明满足设计威力;再对外部干扰对成型的影响进行模拟分析,包括天线罩的影响、壳体的影响等,对形成弹丸的外形及速度进行了分析,提出了改进方案,使EFP的威力满足设计要求。 对于以上每种情况分别对紫铜和钽材提出了合理的装药结构方案。通过对比可知,钽材料的EFP威力比紫铜材料的药型罩威力大2O%～25%。对于威力要求越来越高的战场而言,钽材料是理想的选择。 采用数值模拟的手段缩短了设计周期、节约了研制经费、提高了设计水平。更多还原

【Abstract】 Sense and destroy armor artillery projectile is a kind of smart exactly attacking tank top armor’s projectile which accumulate advanced sense technology ,photoelectron , computer technology , information transacting technology and explosive formed projectile (EFP) technology. EFP warhead technology is the key technology of sense and destroy armor artillery projectile.Test is a traditional way to design a main charge of sense and destroy armor artillery projectile. In this paper, on the basis of others’ , using theory analysis and numerical simulation technology to get well shaped EFPs , and reasonable velocity. We decide the key parameter first: the material of the EFP、 type of detonator and EFP、 the length of detonator, the thickness of cover and so on; then simulate the power of the EFP , the results show us it is satisfied; after that simulate the interference of antenna cover and the shell. Base on the shape and the velocity of the EFP, we bring forward a betterment project, make it satisfy the design request.For both copper and tantalum, we bring forward reasonable projects. There is a 20%~25% betterment between the tantalum and copper projects by contrast. Tantalum is a better choice for the request of battlefield.So the simulation has an advantage in shorting time 、 saving money and improving quality of production.更多还原
