摘要:
采用一种新型线性聚能装药结构，研究了不同炸高时线性聚能装药射流对混凝土墙体的毁伤效应。数值模拟发现，药型罩锥角为80°与50°时，能较好地避免拉断现象。得到了线性聚能装药结构的射流头部速度、侵彻深度随炸高的变化规律。炸高为60 mm时，最佳侵彻深度达130.6 mm。对炸高为60 mm与100 mm时的线性聚能装药进行试验研究。结果表明，炸高100 mm时，侵彻深度达到125.0 mm，与仿真结果吻合较好。验证了该线性聚能装药结构对混凝土墙体的毁伤效果较好。可为线性聚能装药结构的设计与试验研究提供参考。
Abstract:
A new type of linear shaped charge structure was adopted to study the influence of stand-off on the damage of linear shaped charge jet on concrete walls. In numerical simulations, it has found that when the cone angles of the shaped charge are 80° and 50°, it can effectively avoid the phenomenon of pulling and breaking. The variation law of jet head velocity and penetration depth with stand-off for linear shaped charge structure was obtained. The optimal penetration depth reaches 130.6 mm when the stand-off is 60 mm. Experimental study was conducted on linear shaped charge with stand-off of 60 mm and 100 mm. The results show that when the stand-off is 100 mm, the penetration depth reaches 125.0 mm, which is in good agreement with the simulation results. The linear shaped charge structure has been verified to have a good destructive effect on concrete walls. It can provide reference for the design and experimental research of linear shaped charge structures.
