针对危险破甲弹药运输系统的防护问题,采用爆炸式反应装甲作为防爆车厢体内防护射流侵彻的结构。以某制式破甲弹为例,应用非线性有限元程序LS-DYNA研究了反应装甲在不同斜置角时对射流的防护效果。结果表明:增大反应装甲的放置角度,在保证安全的情况下可以大幅减小危险弹药运输系统厢体装甲钢的厚度;当放置角度为60°时,运输系统厢体对装甲钢的厚度要求可以降低70%以上。
In view of the protection of the Dangerous Armor transport system, the explosive reaction armor is adopted as the structure for penetrating the protective jet inside the explosion-proof carriage. Taking a certain type of projectile bomb as an example, the non-linear finite element program LS-DYNA was used to study the protective effect of reactive armor on the jet at different skew angles. The results show that increasing the reaction armor placement angle can greatly reduce the thickness of the armored armored steel of the dangerous ammunition transport system under the condition of ensuring the safety; when the placing angle is 60 °, the thickness of the armored steel body of the transport system compartment requires Can be reduced by more than 70%.
