针对靶场试验无法准确获得穿甲爆破弹对有限厚度钢筋混凝土靶的极限贯穿速度问题,在分析弹丸侵彻有限厚度钢筋混凝土靶破坏特点基础上,进行不同弹着点位置的弹丸穿靶仿真计算。通过对比靶场试验和仿真计算结果,得出该穿爆弹对300mm厚钢筋混凝土靶的极限贯穿速度为250m/s。此外,在常见的计算钢筋混凝土极限贯穿速度经验公式中,美国陆军公式计算结果准确可靠,可用于实际工程中预估穿爆弹对钢筋混凝土靶极限贯穿速度。

Since limit perforation velocity of armor-piercing high-explosive projectile penetrating reinforced concrete with limited thickness cannot be obtained accurately by target range test, and on the basis of analysis of destruction characteristics of reinforced concrete, the penetration progress of different point of impact was simulated. By comparison between test and simulation results, the limit perforation velocity of armor-piercing high-explosive projectile penetrating 300 mm reinforced concrete is 250 m/s. In addition, it is accurate and reliable to use ACE formula to estimate the limit perforation velocity of reinforced concrete with limited thickness, which can be used for engineering application.
