采用自主开发的软件平台EXPLOSION-2D对不同锥角药型罩结构的聚能装药成型进行数值模拟,并得到了聚能装药成型规律以及炸高对聚能装药侵彻厚混凝土靶板的影响.基于侵彻体的性能参数选取了两类侵彻效果较好的聚能装药结构进行侵彻厚混凝土靶板的数值模拟研究.根据侵彻结果设计了一种侵彻厚混凝土靶的聚能装药结构,并进行了相应的实验研究.对实验后混凝土靶板进行剖切,通过混凝土靶的内部破坏情况评估侵彻体对不同位置处混凝土靶的损伤情况,并测量各个位置处的孔洞直径.采用EXPLOSION-2D软件平台对实验工况进行模拟,对比分析实验与数值模拟的结果.对比结果表明该数值模拟技术能够有效地评估混凝土靶板的破坏情况.
The self-developed software platform EXPLOSION-2D was used to simulate the charge shaping of the cone-shaped cover with different cone angle, and the rules of charge shaping were obtained. Based on the performance parameters of penetration, two kinds of chargeable concrete structures with better penetrating effect were selected to study the numerical simulation of penetrating into thick concrete target plate.A penetration concrete target And the corresponding experimental research was carried out.After the experiment, the concrete target plate was cut and the damage of the concrete target at different positions by the penetration body was evaluated by the internal damage of the concrete target, The hole diameter of the hole was simulated.The experimental conditions were simulated by EXPLOSION-2D software platform, and the results of the experiment and numerical simulation were compared.The results show that the numerical simulation technique can effectively evaluate the damage of concrete target.
