杀爆战斗部动态破片威力场分布规律研究
|
摘要
运用LS-DYNA软件对杀爆战斗部破片场数值仿真,研究杀爆战斗部落角、爆高、落速三种因素对破片场分布规律的影响.研究结果表明:动态破片威力场分布受落角和炸高的影响较大,而落速对破片场分布影响相对较小.随着落角的减小,地面破片场的分布呈现规律性变化:圆形→椭圆形→球锥形→大锥角,且杀伤面积和穿甲效率面积呈递减趋势.随着战斗部爆高的增加,杀伤面积和穿甲效率面积,呈现先增大后减小的变化趋势,该战斗部在爆高20m时达到最优值.最后进行终点效应试验验证,研究结果对杀爆战斗部毁伤威力的提高具有一定参考价值.
Using LS-DYNA software,the numerical simulation of the fragmentation field of the blasting warhead was conducted to study the effects of three factors,including the tribal angle,the blast height,and the falling speed on the fragment distribution field.The results show that the dynamic field distribution of dynamic fragmentation is greatly affected by the falling angle and blast height,while the falling speed of the fragmentation has a relatively small impact on fragment distribution.With the decrease of the falling angle,the distribution of ground fragment field shows a regular change:round→oval→ball cone→large cone angle,and the area of killing area and penetrating efficiency show a decreasing trend.With the height of the warheads increased,the area of killing and penetrating efficiency show a trend of increasing first and then decreasing,and the warhead reaches an optimal value at a height of 20 m.Finally,an end-effect test is performed to verify that the results of the study have a certain reference value for the improvement of the damage power of the blasting warhead.
