摘要: 为了在大块度障碍物上快速开孔且孔深和孔径符合要求,提出了一种前后两级均为爆炸成形弹丸 (EFP)装药的新型串联聚能装药结构。分析了装药结构参数对串联EFP侵彻威力的影响,并在此基础上分 别开展了串联EFP装药在不同装药间距与起爆延时条件下侵彻45钢靶实验。实验表明,优化后的串联EFP 装药结构使前后两级EFP装药的侵彻效率大大提高,能对硬目标进行有效破孔。Abstract: Torealizethathunkfraisescanbefastperforatedandtheperforateddepthandwidthareenough, anewtandemshapedchargestructurewasproposedbyusingtwosamestructuresofexplosively- formedprojectile(EFP)shapedcharges.Andtheeffectsofthestructuralparametersonthe tandemEFPchargepenetrationpowerwereanalyzed.Basedontheaboveanalysis,experimentswere conductedfortandemEFPspenetrating45steeltargetsunderdifferentchargespacingsanddifferent initiationdelays,respectively.TheresultsshowthatthetandemEFPchargestructurecangreatlyimprovethepenetrationefficiencyofthetwo- stagetandemshapedchargeanditcanbeusedtoeffectively penetratehardobjects.
