摘 要:在环形聚能装药结构中,单锥罩结构形成的射流中间有堆积现象,断裂前射流拉伸长度有限,而双锥罩射流兼顾了上锥小锥角形成高头部速度,下锥大锥角增大射流有效质量的优点,形成的射流更加细长,头部速度高且不易断裂。基于环形切割聚能装药战斗部,综合考虑上锥角大小、上锥罩占药型罩高的比例、药型罩的高度以及药型罩壁厚对射流侵彻能力的影响,并基于灰关联理论对双锥罩环形聚能装药的优化提供依据,通过数值仿真,研究表明:上下锥角对射流成型影响最大,通过比较,当上锥罩为34°、上锥占罩高比例为40%、药型罩高度为70mm、药型罩壁厚为5mm时,形成的射流头部速度高,且在空气中能够稳定飞行。相比单锥罩结构,双锥罩射流细长,在空气中飞行时间长,对靶板的侵深大于单锥罩射流。There is accumulation in the middle of the jets formed by the single cone liner in the annular shaped charge structure,and the length of the jet is limited before the fracture.The jet of the double cone liner takes both the high head speed formed by upper small angle cone liner and increscent effective mass of the jet formed by the lower cone liner.Therefore,the jet is more slender with high head speed and it is not easy to break.Based on the annular cutting shaped charge warhead,the influence of the upper cone size,the proportion of the upper cone cover,the mask height and the wall thickness of the liner on the penetration capability of jet is considered.It is concluded that the upper cone angle has the greatest influence on the jet molding.By comparison,when the top cone cover is 34°,the proportion of top cone is 40%,the height of the liner is 70 mm and the wall thickness of the liner is 5 mm,the jet head can fly steadily in the air with a high speed.Compared with the single cone liner structure,the jet formed by the double cone liner is long and slender,and has long flight time in the air,its penetration capability is greater than that of the single cone jet.
