TC复合弹对多层A3钢靶穿甲效应的试验与仿真

为提高弹丸的侵彻威力,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,对2种不同结构弹丸侵彻多层A3钢靶的试验结果进行分析研究。运用冲击动力学理论公式,计算TC复合弹和制式弹在冲击接触钢板瞬间的冲击压力并进行对比。重点分析对比弹头结构、材料对多层A3钢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钢板的侵彻深度、孔径,以及侵彻后弹芯剩余质量进行了对比分析。运用ANSYS/LS-DYNA有限元软件对侵彻过程进行模拟仿真,并与试验结果对比。结合数值模拟的结果,分别从余速和弹芯剩余质量上进一步分析TC复合弹的侵彻能力。结果表明,TC弹头对弹芯的保护效果明显,为陶瓷材料应用于其他战斗部提供了依据。

Simulation and Experimental Investigation on Armor-piecing Performance ofTC Composite Projectile to Multilayer A3 Steel Plates Targets

In order to improve the penetration power of projectile,the armor-piercing performance of 30mm projectile with a toughened TC warhead to the multilayer A3 steel plates targets was experimentally researched under DOP method,and the projectile was compared to the standard projectile.The impact-dynamic formula was applied,and the sudden impact pressure of ceramic plates shocked by TC composite projectiles and the standard projectiles was calculated and compared.The effects of warhead structures and materials on armor-piercing performance to the multilayer A3 steel plates targets were analyzed and compared.Under the same conditions,the aperture,the depth of perforation and the residual mass of bullet core on the armor plates of TC composite projectiles were compared with those of the standard projectiles.The penetration process was simulated by ANSYS/LS-DYNA,and the simulation results were compared with the test results.Combined with the simulation results,the penetration performance was further analyzed in terms of the leaving velocity and the residual mass of bullet core.The results show that the TC warhead has a great effect on the protection of bullet core,and the study offers a foundation for ceramic applied in other warheads.
