摘要:
为了揭示变形后主装药的起爆方式对可变形定向战斗部威力的影响,该文利用通用有 限元软件LS-DYNA3D 对可变形定向战斗部的变形和定向飞散过程进行了数值模拟,研究了主 装药径向和轴向起爆方式对破片速度和密度增益的影响。结果表明:径向起爆时,起爆点与端 面中心的距离等于主装药半径,两起爆点与端面中心所形成的夹角为45毅时,破片速度增益最 大;轴向起爆时,两端同时起爆优于一端起爆和线起爆。与传统周向均布破片战斗部相比,目标 方位上的破片密度增益为78. 7%,速度增益为32. 2%。
Abstract:
In order to reveal the influence of initiation modes of the main charge on the power of de- formable warhead,the deforming and projectile processes of the deformable warhead are numerically simulated by the finite element analysis software LS-DYNA3D, and change laws of the fragment velocity and densities enhancement under the different radial and axial initiation modes of the main charge are studied here. The results show that, under the radial initiation, the enhancement of fragment velocity is maximum when the distance from the initiation point to the center of the end face equals the radius of main charge and the angle between the two lines formed by the initiation point and the center of the end face is 45°. The both ends initiation mode is better than one end initiation mode and the line initiation mode under the axial initiation. Comparied with the uniform warhead,the fragment density enhancement is 78. 7% and the fragment velocity enhancement is 32. 2% in the target direction when initiated by the both ends mode of the main charge.
