利用弹头变形识别枪击5mm钢化玻璃时序的研究

The study of the sequence of the shooting 5mm steelglass by warhead deformation

选用54式手枪、77式手枪和QSZ92式9mm手枪,分别垂直射击5mm钢化玻璃,分析弹头在贯穿玻璃后的变形和玻璃平面的痕迹特征。通过实验研究,统计并分析相关数据,得出了首发弹和非首发弹形成的弹孔痕迹以及弹头的平面痕迹特征的区别,根据弹头变形识别枪击钢化玻璃的时序。由于各种枪支不同的性能,比较多种弹头的痕迹特征,找出影响弹头痕迹特征的主要因素。

This paper analyses the characteristics of the warhead＇ s deformation after penetrating theglass and the surface ofglass by choosing 54 pistol,77pistol and QSZ92pistol to shoot 5mm temperedglass vertically. This paper summarizes the differences between the starting and non-starting cartridge marks and the plane trace characteristics of the warhead by conducting experiments. The sequence of shooting tempered glass can be recognized according to the warhead deformation. Due to the different performance of various kinds ofguns, the main factors affecting the characteristics of the warhead are found by comparing the characteristics of different kinds of warhead.
