破片和冲击波复合作用对装甲板毁伤敏感性分析

Sensitivity Analysis of Compound Action of Fragments and Shock Waves on Armor Plate Damage

为了分析破片和冲击波复合作用毁伤因素下对装甲板毁伤面积影响程度,通过正交试验并进行了数值模拟,对仿真结果进行了灰关联分析,得到破片直径、破片入射速度、破片入射角度、装甲板厚度、炸高与装甲板毁伤面积的关联度。结果表明:破片和冲击波复合作用对装甲板毁伤面积影响程度排序为:破片直径d>破片入射角度α>破片入射速度V>炸高H>装甲板厚度h,研究结果可为破片和冲击波复合毁伤研究及装甲防护提供参考。

In order to analyze the influence of fragments and shock wave combined damage factors on the damage area of armor deck, the orthogonal test and the numerical simulation was carried out. The Grey correlation analysis of simulation results was carried out, and the correlation degree of fragment diameter, fragment incident velocity, fragment incident angle, thickness of armor deck, explosion height and the damage area of armor deck was obtained. The results show that the order of the damage area affected by the combined action of fragments and shock wave is: fragment diameter d >fragment incident angle α>fragment incident velocity V >explosion height H >armor plate thickness h . The analysis results can provide references for the study of composite damage of fragments and shock wave and armor protection.
