Abstract

In this research, ballistic performance of composite armors composed of ceramic-polyurea-aluminum layers was investigated. First, in order to validate the simulation outcomes, we used two references where targets coated with ceramic-aluminum and polyurea-aluminum layers were investigated. Given the experimental designs, ballistic performance of the targets was evaluated as those were hit by a flat-nose projectile with a diameter of 7.62 mm and a length of 25.4 mm at a projectile velocity of 950 m/s using the LS-Dyna software. Subsequently, an analytical formulation was developed to estimate the ballistic limit velocity and residual velocity of the projectile. Afterwards, seeking to optimize the thicknesses of different layers on the designed targets, the residual velocity of the projectile and surface density were introduced, as objective functions, into the response surface methodology where the layer thicknesses were taken as optimization variables to check for the effect of the layer materials on the objective functions.

陶瓷-聚氨酯-金属层复合靶弹道性能的数值分析研究及层厚优化

摘要研究了陶瓷-聚氨酯-铝复合装甲的弹道性能。首先，为了验证模拟结果，我们使用了两个参考文献，其中研究了陶瓷铝层和聚氨酯铝层涂层的目标。根据实验设计，利用LS-Dyna软件对直径为7.62 mm、长度为25.4 mm的平鼻弹在950 m/s弹速下命中目标的弹道性能进行了评估。随后，建立了弹丸弹道极限速度和剩余速度的解析公式。然后，为了优化设计目标上不同层的厚度，将弹丸剩余速度和表面密度作为目标函数引入响应面方法，并以层的厚度作为优化变量，考察层材料对目标函数的影响。
