钨铜聚能粒子流的侵彻特性研究

为研究钨铜聚能粒子流的侵彻特性,对钨铜多孔药型罩和紫铜板药型罩的侵彻性能进行了试验研究,测试了钨铜聚能粒子流侵彻铝板的穿深与时间关系曲线。试验结果表明:在1倍装药口径炸高下,钨铜聚能粒子流侵彻铝靶的穿深比紫铜板射流侵彻铝靶的穿深要提高31%。利用最小二乘法对穿深与时间关系曲线进行拟合,拟合结果表明穿深与时间的关系呈乘幂形式。结合侵彻试验结果,确定了钨铜聚能粒子流的最后侵彻速度为1657.8m/s。这为多孔药型罩聚能装药的设计提供一定的指导意义。

PENETRATION CHARACTERISTICS OF W-Cu SHAPED CHARGE PARTICLES JET

In order to study the penetration characteristics of W-Cu shaped charge particles jet,the penetration performances of W-Cu porous liners and red copper plate liners were tested,and the curve of penetration depth and time for W-Cu shaped charge particles jet penetrating in aluminium target was measured.The test results showed that the penetration depth of W-Cu shaped charge particles jet could increase 31% than the penetration depth of red copper plate shaped charge jet in aluminium,when the blasting height was equal to charge diameter.The curve of penetration depth and time was fitted by the least square method.The fitting results showed that the relationship between penetration depth and time was the power form.The final penetration rate of W-Cu shaped charge particles jet was 1657.8m/s,which was confirmed by the penetration test results.It could provide a certain guiding significance for the design of shaped charge with porous liners.
