摘　　要：为了满足定向战斗部在引战配合时的起爆控制要求,针对定向战斗部预制破片的飞散规律,提出了一种基于六分位激光引信探测定位的起爆控制建模方法。该方法通过六分位激光探测模型对目标方位的准确识别,实现对定向战斗部起爆方位的控制。为了研究不同起爆方式对战斗部威力的影响,利用LS_DYNA有限元仿真软件,模拟研究了在不同起爆方式下战斗部的破片飞散规律,找到最佳起爆控制方位。仿真结果表明:偏心60°双线起爆下定向破片速度增益为9.32%,定向毁伤区域约为120°;偏心120°双线、三线和等距三线起爆下定向破片速度增益分别为8.44%、10.56%和11.53%,定向毁伤区域约为60°。建立的探测模型可以与定向战斗部的起爆控制有效配合,达到对目标的最佳毁伤。In order to meet the detonation control requirements of the aimable warhead during the fuze-warhead cooperation,a detonation control modeling method based on the detection and positioning of the hexagon laser fuze is presented for the dispersion rule of the prefabricated fragments of the aimable warhead.This method achieves the control of the detonation orientation of the aimable warhead by accurately recognizing the orientation of the target through the hexagon laser detection model.At the same time,in order to study the influence of different initiation methods on the performance of the warhead,the LS_DYNA finite element simulation software is used to simulate and study the fragments dispersion rule of the warhead under the different initiation methods and find the best initiation control position.Simulation results show that the directional fragment velocity gain under the eccentric 60°two lines Initiation is 9.32%,and the directional damage area is about 120°;the directional fragment velocity gains under eccentric 120°two lines,three lines and equidistant three lines initiation are 8.44%,10.56%and 11.53%,respectively,and the directional damage area is about 60°.The established detection model can effectively cooperate with the detonation control of the aimable warhead to achieve the optimal damage effect on the target.
