摘要
为研究非致命动能弹头部冲击响应,分析弹丸冲击速度和最大冲击力对头部损伤程度的关系,提高弹丸安全服役性能,依托非致命武器钝击效应实验室,进行3种不同口径、质量、形状和硬度的动能弹丸刚性壁冲击实验。收集了弹丸对刚性壁的最大冲击力数值,计算了弹丸着靶和回弹速度及能量传送比。利用高速摄像系统,构建了弹丸冲击变形量和时间的关系曲线,分析了弹丸硬度和最大接触面积对冲击力的影响。结合北约非致命动能弹头部损伤评估标准和GJBZ20262—95防暴动能弹威力标准,构建了弹丸着靶速度与最大冲击力线性拟合关系,得出了只造成头部轻度损伤的弹丸临界冲击速度和最小安全射击距离,研究结果可为不同类型动能弹药的安全服役提供支撑。
The rigid wall impact experiments of kinetic energy projectile with three different calibers,masses,shapes and materials were carried out by the non-lethal weapon blunting effect laboratory in order to study the head impact response of non-lethal kinetic energy projectiles and to analyze the relationship between impact velocity and maximum impact force on head injury and improve the safe service performance of the projectiles.The maximum impact force,the impact velocity,the rebounding velocity and the energy transfer ratio were collected.Using the high speed camera system,the relationship curve between the deformation and the time of projectile impact was constructed.The influence of projectile hardness and maximum contact area on impact force was analyzed.Combined with the head injuries assessment of non-lethal projectiles standard of the North Atlantic Treaty Organization and GJBZ20262—95 riot kinetic energy projectile power standard,the linear fitting relationship between the projectile impact velocity and the maximum impact force was constructed.The critical impact velocity and minimum safe shooting distance of the projectile are afterwards obtained,causing slight head damages.The research results can provide solid support for the safe service of different types of kinetic energy projectiles.
