摘要:
为了研究防护条件下人员的钝性损伤机理,明确步枪弹撞击防弹衣后所产生压力波的特性,实验中采用4 ℃,10%浓度配比,尺寸为300 mm×300 mm×300 mm且附着NIJ Ⅲ级防弹衣的明胶块作为模拟靶标,在100 m射距下射击3发5.56 mm SS109步枪弹。利用枪弹入靶速度和压力测试系统同步测试,共获得了3组靶标内部压力波数据。通过对数据进行处理和分析得出以下结论:(1)压力波峰值约为506 kPa,上升时间约为13 μs,持续时间约为60 μs;(2)压力波的传播速度约为1 000 m/s,与子弹初速无关;(3)压力波峰值随传播距离增加呈指数衰减。
Abstract:
In order to study the blunt injury mechanism of persons in protective conditions,and clarify the characteristics of pressure waves in the rifle projectiles impacting the body with armor.The test in this paper adopts the gelatin at 4 ℃,10% concentration ratio,and in 300 mm×300 mm×300 mm size with NIJ III bullet proof armor as the simulated target,shooting three 5.56 mm SS109 bullets in 100 meters.By means of the velocity of bullet test system and the pressure test system of synchronization,three sets of data of inner pressure curves in target are obtained.Through processing and analyzing the data,this paper concludes:(1)the peak value of pressure wave is about 506 kPa,the rising time is about 13 μs,and the time of duration is about 60 μs;(2)the speed of pressure wave propagating is about 1 000 m/s,and it has nothing to do with the bullet initial velocity;(3)the peak value of the exponential of pressure wave is in attenuation with the change of distance.
