基于爆炸成型弹丸(EFP)和环形侵彻体的特点,提出了一种能够同时形成两种毁伤元素的装药结构。利用ANSYS/LS-DYNA软件对该结构进行了数值模拟,并对其主要影响因素进行了对比分析。研究结果表明:当中间药型罩材料密度大于环形药型罩材料密度时,能够使环形侵彻体的速度大于中间EFP的速度;当偏移量d为2mm时,环形侵彻体头部偏转角几乎为0°,其形态较好,侵彻能力较强。研究结果可为成型装药结构的研究提供一种新的参考。

Based on the chanacteristics of EFP and annular penetrator, a combined charge structure which can form two kinds of damage element at the same time was proposed. ANSYS/LS-DYNA software was used to simulate the combined charge structure, and influence factors were analyzed. The results show that when the middle liner material density is greater than the annular liner, the speed of annular penetrator is faster than that of the middle EFP, and when the offset d is 2mm, the deflection angle 0 of annular penetrator head is almost 0°, the shape is better and the penetration ability is stronger. The research results can provide a new reference for studying on the charge structure.
