摘　　要：选取了8种偏心起爆方式,利用AUTODYN软件进行数值模拟,研究偏心起爆方式对复合装药战斗部定向威力的影响。计算获得了起爆点数、偏心夹角等因素对复合装药战斗部形成的定向破片特征参数的影响规律;找出了最优偏心起爆方案(偏心夹角为45°的偏心2点起爆),相比中心点起爆,该方案形成的定向破片平均动能增益达52.45%,平均速度增益达8.76%。Eight eccentric initiation modes of composite charge structure were designed to obtain the directional control law.The numerical simulation was carried out in order to study the influence of several eccentric initiation modes on the directional power of composite charge warhead by using AUTODYN software.The influence of eccentric angle and number of initiation points on the characteristic parameters of directional fragments formed by composite charge structure was obtained.The optimal eccentric initiation scheme obtained from the study was the eccentric two-point initiation mode with 45°eccentric angle.Fortunately,the directional fragments formed have an average kinetic energy gain of 52.45%and an average velocity gain of 8.76%,compared with the central point detonation mode of the charge.
