摘要

摘要: 为调控对地弹药破片杀伤威力场，研究了一种鼓形战斗部在静爆和动爆下的威力特性。采用数值模拟研究了端面中心单点、中心单点两种起爆方式下，鼓形战斗部相较于同口径圆柱形战斗部在静爆下的破片威力特性及动爆下对地面装甲车辆目标的毁伤面积。在此基础上，调整鼓形战斗部起爆方式为偏心两线同时起爆、偏心两线序贯起爆及偏心两线同时-序贯起爆，计算了不同偏心起爆下鼓形战斗部静爆时的破片速度、飞散角和动爆时对车辆目标的毁伤面积及有效破片落地动能分布。研究表明，相比于同口径的圆柱形战斗部结构，鼓形战斗部的破片飞散角增大了55.98%，对地面军用车辆的毁伤面积最大增大了59.3%；相对于偏心两线同时起爆，偏心两线同时-序贯起爆的鼓形战斗部破片飞散角增大了18.0%，破片飞散的离散程度提高了11.48%；相对于装药中心单点起爆，偏心两线序贯起爆下鼓形战斗部的毁伤面积受炸高影响较小，在落角50°、落速200 m/s、炸高为9 m时的毁伤面积达47.15 m²。通过调整战斗部的结构和起爆方式，可有效增大破片的飞散角，增大破片对目标的覆盖面积，提高战斗部的毁伤效能。

Abstract: To adjust the fragment lethality field of the anti-ground ammunition, the paper studies the power characteristics of a drum-shaped warhead under static and dynamic detonation. Aiming at the ground armored vehicles, the damage efficiency of the drum-shaped warhead under different initiation modes is analyzed. The fragment power characteristics of a drum-shaped warhead under static detonation and the damage area to vehicle target under dynamic detonation are studied by numerical simulation under two initiation modes of end face center single point and center single point compared with cylindrical warhead of the same caliber. On this basis, further by adjusting the drum-shaped warhead initiation mode into three kinds of eccentric two-line synchronous initiation, eccentric two-line sequential initiation and eccentric two-line synchronous-sequential initiation. The fragment velocity and dispersion angle of the drum-shaped warhead during static detonation, the damage area to the vehicle target and the distribution of the effective fragment landing kinetic energy during dynamic detonation are calculated under different eccentric initiation. The effect of adjusting the detonating mode on the destruction power field of the fragment of the drum-shaped warhead is analyzed by comparing the power characteristics of the fragment of the drum-shaped warhead during the static detonation and the damage results of the vehicle target during dynamic detonation with the corresponding results under the end face center single-point initiation of the drum-shaped warhead. The results show that compared with the cylindrical warhead structure with the same caliber, the fragment dispersion angle of the drum-shaped warhead is increased by 55.98%, and the damaged area of the ground military vehicles is increased by the maximum 59.3%. Compared with the eccentric two-line synchronous initiation, the drum-shaped warhead with eccentric two lines synchronous-sequential initiation can increase the fragment dispersion angle by 18.0%, and increase the dispersion of fragments by 11.48%. Compared with the single-point initiation of charge center, the damage area of the drum-shaped warhead under eccentric two-line sequential initiation is less affected by the burst height, and the damage area reaches 47.15 m² when the falling angle is 50°, the falling velocity is 200 m/s and the burst height is 9 m. By adjusting the structure and the initiation mode of the warhead, the dispersion angle of fragments can be effectively increased, the coverage area of fragments to the target can be increased, and the damage efficiency of the warhead can be improved.
