为研究杀爆榴弹自然破片的破片形状特性、速度衰减能力、侵彻能力等基本终点威力参数,通过理论分析、试验验证,得到了1~4 g自然破片的平均迎风面积、阻力系数、衰减系数及对不同铝板的极限穿透能力,建立了终点毁伤模型。研究结果表明,1~4 g自然破片的形状系数为4.96×10^-3 m²kg^-2/3,在空气中的速度衰减系数为0.022 m^-1,阻力系数为0.89,侵彻单位铝板消耗的能量为4.4×10⁸ J/m³。该试验方法的建立,可指导大质量自然破片的终点参数研究,进一步完善毁伤模型,为火力规划与评估提供数据支撑。

In order to study the terminal effect parameters of the natural shading including the number of debris-shaped systems, speed attenuation capability and intrusive ability, the paper builts the end-of-term damage model and gets the power parameters of the natural shading ranging 1~4 g, including the average wind-facing, resistance factor, attenuation factor, the speed of penetration for the limits of different aluminum plates, through the theory of analysis, test and verification. The results show that shape factor of the natural shading ranging 1~4 g is 4.96×10^-3 m²kg^-2/3; attenuation factor is 0.022 m^-1; resistance factor is 0.89; the consumed energy of encroaching each aluminum plate is 4.4×10⁸ J/m³.The establishment of the test method can refer to the study of the end point parameters about large natural shading, completes the damage model and supports for the number of supplies for fire planning and evaluation.
