摘要
通过对大量杀爆弹弹丸战斗部自然破片外形数据的统计,分析了其分布规律,确定了建模方向。利用ANSYS/LS-DYNA有限元软件,比较分析了几种典型破片的形状对装备损伤的影响,进而确定了在装备战斗损伤机理仿真研究中的破片模型。
According to the statistic data of nature fragment form of pill warhead, the distributing law of which was analyzed, and three general models were selected. Based on that, the effect of fragment form on penetration was analyzed by ANSYS/LSDYNA. And the fragment form used in later materiel battle damage mechanics study was determined at last.
