为了进一步提高药型罩有效射流量以及对钢靶的侵彻深度,设计了五种不同中心圆柱高度的串联药型罩,并利用有限元软件LS-DYNA对不同中心圆柱高度的串联药型罩装药结构射流的成形以及对钢靶的侵彻过程进行了数值模拟研究,然后配以相应的炸药装药进行试验研究。对研究结果进行了简要的比较分析,结果表明,合适的中心圆柱高度要比太高或者太低的中心圆柱高度的装药结构形成的射流头部速度更高,侵彻钢靶更深,且数值模拟与试验研究所得结论基本吻合。

To further improve effective jet of liner and depth of steel target penetration, five structures of series liner were designed by different center cylindrical height. Numerical simulation of different center cylindrical height of liner series' jet forming and the penetration of steel targets was done with the finite element software LS-DYNA, then accompanied by the appropriate test of explosive charge. Essential analysis and conclusion have been drawn out. It can be concluded from the results that the velocity of front jet formed by the charge structure with proper center cylinder height is higher that the one with too high or too low center cylinder height, and the penetration of the former is deeper, the numerical simulation basically agrees with the experimental study.
