摘要

通过对杀爆战斗部爆炸后破片运动及冲击波传播的研究,为提高破片和冲击波相遇位置的计算精度,理论推导了新的计算方法。采用VisualC++开发破片与冲击波运动规律计算系统使计算方便。运用AN-SYS/LS-DYNA数值模拟了某预制破片战斗部爆炸后破片与冲击波的运动,数值模拟与该模型计算结果相符,较以往计算模型精度提高了8.3%。

关键词： 破片; 冲击波; 运动规律; LS-DYNA

Abstract

According to study of shock wave propagation and fragment movement after explosion of blast fragmentation warhead, a more accurate way was provided for calculation of fragments and shock wave propagation distance and the time delayed. A computing system of fragments and shock wave's movement was developed by using Visual C++. It makes calculation be more convenient. Movement of preformed fragments and shock wave after explosion was simulated. The results show that the simulation tally with the new calculation model and the accuracy is improved by 8.3%.

Key words： fragment; shock wave; motion law; LS-DYNA
