穿甲弹是应用较多的、更为有效的击毁装甲目标的弹种,为抵御穿甲弹侵彻,主战坦克上带有各式附加装甲,如复合装甲。研究复合装甲三层材料厚度比对其抗侵彻性能的影响,基于ANSYS/LS-DYNA软件在显示动力分析上显现出的良好性能及长杆弹穿甲理论,建立多组数值模拟模型,研究复合装甲的抗侵彻性能,并得出:三层材料厚度比为5:3:1时,抗侵彻性能最优。对文中所述数值模拟进行理论计算,仿真计算结果与理论计算结果一致,所得结论可对优化武器攻击与防护体防护提供参考。

The armor piercing projectile is a relatively effective weapon to destroy the armored target. In order to resist penetration of the armor piercing projectile, there are various additional armor, such as composite armor, on the main battle tank. The influence of the thickness of three layers of composite armor on its penetration resistance is studied. Based on the good performance of the ANSYS/LS-DYNA software and the theory of long rod projectile penetration, a multi group of numerical simulation models are established to study the penetration resistance of the composite armor, and the resistance of the three layers to the thickness ratio is 5:3:1. The penetration performance is optimal. The numerical simulation in this paper is calculated, and the simulation results are in agreement with the theoretical results. The conclusions obtained in this paper can provide reference for the optimization of weapon attack and protection body protection.
