摘　　要：为了分析土质墙体障碍物对狙击子弹弹道的影响,利用LS-DYNA软件,建立了在100 m、500 m、1 000 m三种射程,落角为15°、45°、85°、90°,总计12种情况下的弹道数值模拟模型,分析了射程和落角对其侵彻深度、水平偏移、侵彻速度、偏移速度的影响。研究结果表明,狙击弹侵彻土质墙体的终点弹道具有一定的随机性,其射击精度和毁伤效果具有很大的不确定性。该结果为狙击作战和指挥提供了一定的理论指导。In order to analyze the effect of sniper bullet trajectory on penetrating the thick soil wall obstacle,the models of numerical simulation was established, in which the penetration depth, the horizontal offset,penetration velocity,the offset velocity were obtained in three kinds of range of 100 m,500 m,1 000 m,with the drop angle of 15°,45°,85°,90°,and the total of 12 numerical simulation of terminal ballistic models. The results show that sniper ammunition＇s terminal ballistics into the wall has some randomness,and their shooting accuracy and damage effects are uncertainty. The results can provide a theoretical guidance for sniper operations and command.
