叙述了钢球破片以高速（1200～2200m/s)侵彻多层组合靶实验的物理现象.分析了钢球机械性能和着速对击穿能力的影响.得出了在一定破片质量下着速与击穿概率的关系曲线。实验证实了在高速侵彻条件下，用多层组合靶比用等强度单层靶更符合实际更科学的观点。本研究结果为导弹杀伤战斗部和杀伤弹丸的设计提供了可靠的依据。
Describes the physical phenomenon that the ball fragments penetrate the multilayered composite target at high speed (1200 ~ 2200m / s), and the influence of the mechanical properties and holding speed of the ball on the breakdown capability is analyzed. And breakdown probability curve. Experiments show that it is more practical and scientific to use multi-layer composite targets than single-layer targets with the same strength under high-speed penetration. The results of this study provide a reliable basis for the design of missile anti-personnel warhead and anti-personnel projectile.
