    摘要:

    为研究钢筋混凝土靶厚度对横向效应弹(Penetrator with Enhanced Lateral Effect, PELE)侵彻效果的影响, 采用ANSYS/LS-DYNA 3D软件, 对PELE侵彻破坏不同厚度的钢筋混凝土(Reinforced Concrete, RC)靶进行了数值计算。计算结果表明:利用质量和结构都相同的PELE以800 m·s-1的速度垂直撞击混凝土靶板, PELE可最大穿透80 cm厚的靶板, 在该范围内, 靶板由薄变厚时, 弹体破碎愈加严重, 弹体剩余轴向速度逐渐降低; 对靶的侵彻随靶厚的增加, 靶破坏效应先增强, 然后减弱; 当靶厚超过80 cm时, 弹体的动能全部消耗于侵彻过程中。为验证仿真结果, 进行了实弹实验, 实验结果也表明:对靶的侵彻随靶厚的增加, 破坏效应先增强, 然后减弱, 35 cm厚的靶板破坏最严重; 验证了模拟结果的正确性和可靠性。

    Abstract:

    In order to study the influence of the reinforced concrete target(RC) thickness on penetrator with enhanced lateral effect(PELE)penetrating, the different thickness RC impacted with the velocity of 800 m·s-1 was simulated by LS-DYNA 3D software. Results show that PELE can penetrate the 80 cm thickness target at large. In this range, PELE body shell residual length is shorter with the target getting thicker when PELE could penetrate the targets, and the residual axial velocity of PELE decreases at the same time. With increase of target thickness, the undermining effect of penetration first increases, then decreases. The kinetic energy consumes totally in the penetration process when the targets thickness is over 80 cm. The experiment was carried to verify the simulation results. The experimental and simulated results both show that the 35 cm thickness target is damaged most severely, implying that the simulation are correct and reliable.
