多层异质复合靶板抗侵彻性能试验及结构优化设计

针对多层异质复合靶板结构优化设计,对10 mm氧化铝陶瓷/10 mm芳纶板/6 mm 616装甲钢、10 mm氧化铝陶瓷/6 mm 616装甲钢/10 mm芳纶板2种结构抗14.5mm穿甲弹穿深(DOP)的性能进行了试验分析,对同工况下弹丸侵彻复合靶板进行了数值模拟。在验证数值模型的基础上,结合配方均匀设计方法,建立了相同面密度下复合靶板结构等效质量防护系数回归模型,分析了各层厚度系数对复合靶板防护性能的影响规律,完成了复合靶板结构的优化设计。结果表明,面密度为9.748 g/cm²的复合靶板,最优结构为6.5 mm氧化铝陶瓷板/1.8 mm芳纶/9.1 mm装甲钢,试验验证了优化设计结果的可靠性。

Anti-penetration Performance Test and Structural Optimization Designof Multilayer Heterogeneous Composite Target-plate

For the optimal design of multilayer heterogeneous composite target structure,the test analysis of two structures resistant to 14.5 mm armor-piercing projectile was carried out,namely the structure of 10 mm alumina ceramics/10 mm aramid plate/6 mm 616 armor steel and the structure of 10 mm alumina ceramics/6 mm 616 armor steel/10 mm aramid plate. The projectile penetrating into the composite target plate under the same working conditions was simulated. Based on the verification of the numerical model and the formula uniform design method,a regression model for the equivalent mass protection-efficiency of the composite target plate structure was established under the same areal density. The influence of the thickness coefficient of each layer on the protective performance of the composite target plate was analyzed,and the optimization design of the structure was carried out. The results show that the composite target plate with an areal density of 9.748 g/cm² has an optimal structure of 6.5 mm ceramic plate/1.8 mm aramid plate/9.1 mm armor steel. The reliability of the optimized design method was verified through experiment.
