Tc复合弹对陶瓷/A3钢复合靶穿甲效应的试验研究

为提高弹丸对陶瓷复合装甲的侵彻威力,在30 mm制式弹弹头部采用增韧Tc材料,并与制式弹进行对比。采用DOP试验方法,结合冲击动力学理论和陶瓷材料特性,研究了2种不同结构弹丸对陶瓷/A3钢复合靶的穿甲效应,重点分析对比弹头材料、结构对陶瓷/A3钢复合靶的穿甲效应的影响。在相同条件下,对制式弹和Tc复合弹对A3钢板的侵彻孔径、深度,以及侵彻后弹芯剩余质量进行了对比分析。采用ANSYS/LS-DYNA进行模拟仿真,模拟结果与试验结果基本吻合,结合仿真结果,从弹芯剩余质量上对弹丸的侵彻能力进一步分析,Tc复合弹对弹芯保护的效果明显,为陶瓷材料应用于其他战斗部提供依据。

Experimental Investigation on Armor-piecing Performance of Tc Composite Projectile to Ceramic Composite Targets

In order to improve the penetration power of the projectile to the ceramic composite armor, the armor-piercing performance of 30mm projectile with a toughened Tc warhead to the ceramic/A3 steel composite targets has been experimentally researched by adopting DOP method in comparison with the standard projectile. It mainly analyzes and compares the effects on armor-piercing performance to the ceramic/A3 steel composite targets in the context of different warhead structures and materials. Under the same conditions, a comparative analysis of the aperture and the depth of perforation as well as the residual mass of bullet core on the armor plates has been conducted. A simulation has been built and computed by ANSYS/LS-DYNA, whose results mostly meet the test results. In combination with the simulation results, further analysis on the penetration performance is conducted in terms of the residual mass of bullet core. The results show that the TC warhead has a conspicuous effect on the protection of bullet core, which offers grounds for its being applied to other warheads.
