摘　　要：为了研究狙击弹射击钢化玻璃后目标的准确性,利用ANSYS/LS-DYNA有限元软件对比了狙击弹以不同入射角侵彻玻璃后质心的位移、弹轴偏转大小,描述了狙击弹穿透玻璃的飞行姿态,分析了子弹穿透玻璃的偏转大小,为狙击手击杀歹徒或恐怖分子提供参考。结果表明,随着入射角角度的增加,狙击弹穿透玻璃后趋于水平,质心水平方向位移和偏转距离增大;入射角在0°~45°时,子弹穿透玻璃后飞行0.4m,子弹垂直位移在29.8cm~43.3cm之间,偏转距离的范围在1.5cm~3.36cm之间。In order to study the accuracy of the target after the sniper shot the tempered glass,ANSYS/LS-DYNA finite element software is used to compare the centroid displacement and axis deflection of the sniper bullet penetrating the glass with different incident angles.The flight attitude of the sniper bullet penetrating the glass is described,and the deflection of the bullet penetrating the glass is analyzed,which provides a reference for the sniper to kill the gangsters or terrorists.The results show that with the increase of incident angle,the sniper projectile tends to be horizontal after penetrating the glass,and the horizontal displacement and deflection distance of the centroid will also increase.When the incident angle is 0°~45° and the bullet flies at 0.4 m after penetrating the glass,the vertical displacement of the bullet is between 29.8 cm and 43.3 cm,and the deflection distance is between 1.5 cm and 3.36 cm.
