W型、N型反应装甲对聚能射流干扰性能研究
|
摘要
为解决单层、双层爆炸反应装甲对聚能射流干扰不彻底、仍有逃逸射流侵彻主战坦克装甲,以及双层平行反应装甲与楔形反应装甲面对聚能射流垂直侵彻的问题,根据反应装甲爆轰阶段对聚能射流的干扰机理,建立W型、N型布置的3层爆炸反应装甲结构模型,通过使用ANSYS/LS-DYNA软件进行三维数值模拟仿真。结果表明:当入射角度为45°时,N型反应装甲干预聚能射流的能力优于W型反应装甲,干预射流开坑深度能力提高了3.17倍;当入射角度为90°时,W型反应装甲干预射流的能力优于N型反应装甲,干预射流开坑深度能力提高了1.81倍。该仿真可为未来新型爆炸反应装甲设计、打击新型反应装甲的破甲导弹战斗部设计、研制提供参考。
In order to solve the problem of incomplete interference of single-layer, double-layer explosive reaction armor with shaped jet, the penetration of escape jet into main battle tank armor, and the vertical penetration of shaped jet by double-layer parallel reactive armor and wedge reactive armor, a three-layer explosive reactive armor structure model with W-type and N-type arrangement was established according to the interference mechanism of shaped jet in the detonation stage of reactive armor. Three-dimensional numerical simulation was carried out using ANSYS/LS-DYNA software. The results show that when the angle of incidence is 45°, the capability of N-type reaction armor to interfere with shaped jet is better than that of W-type reaction armor, and the ability of intervening jet penetration is increased by 3.17 times. When the incident angle is 90°, the ability of the W-type reaction armor to cope with the jet is better than that of the N-type reaction armor, and the capability of drilling the pit depth is increased by 1.81 times.The simulation can provide a reference for the future design and development of new explosive reactive armor and armor-piercing missile warhead against new reactive armor.
