摘要/Abstract

摘要： 为研究杀伤战斗部的空炸威力，建立战斗部有限元模型和破片着地坐标计算模型，利用有限元分析软件ANSYS/LS-DYNA对战斗部动态起爆过程进行了数值模拟。根据模拟得到的破片初速和飞散方向，结合破片在空气中的速度衰减公式以及对无防护有生目标的78 J动能杀伤标准，计算出有效杀伤破片在地面的坐标，并对不同炸高条件下有效杀伤破片在地面目标靶上的分布情况进行分析。研究结果表明：炸高为8 m左右时，战斗部满足杀伤威力指标要求；仿真结果与试验结果基本吻合。

Abstract: A finite element model of warhead and a calculation model of ground coordinate of a fragment are established to give full play to the air burst power of antipersonnel warhead, and the dynamic detonation of warhead is numerically simulated by using ANSYS/LS-DYNA software. According to the initial velocity and flying direction of fragments in simulation, the velocity attenuation formula of fragment in air and the 78 J killing criterion of personnel, the coordinates of the effective lethal fragment on the ground are calculated, and the distribution of the effective lethal fragments on the ground targets at different burst heights is analyzed. The results show that the warhead meets the lethality requirements when burst height is about 8 m. The experimental results are in good agreement with the simulated results. Key
