摘要
针对目前的弹药销毁状况,为了减轻直接爆破的环境压力,利用理论分析及数值模拟的方法,首先对设计的简易乳化炸药线型切割器的药型罩材料进行确定,数值模拟表明:铝质药型罩所形成的射流侵彻能力要比紫铜材质的提高28%,而后利用ANSYS数值模拟得出该切割器最佳炸高为15 mm。最后对乳化炸药线型切割器切割薄壳弹药的过程进行数值模拟,证明该切割器可以达到切去弹药外壳而不产生剧烈爆轰及高速破片的效果。
In order to minimize the environmental pressure caused by direct blasting resulting from existing ammunition destruction conditions,theoretical analysis and numerical simulation were used to determine material of linear shaped charge cutter of emulsion explosive.Simulation results show,that penetration ability of the jets formed by the aluminum coating is 28%higher than that of the copper.Then ANSYS software assesses to obtain the optimum blast height as 15 mm.Finally,the cutting process of thin shell ammunition by the linear cutter of emulsion explosive was simulated.It has been proved that the designed cutter can ensure the effect of getting rid of the shell of ammunition without generating violent detonation and high-speed fragment.
