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Visual C++开发破片与冲击波运动规律计算系统使计算方便。运用ANSYS/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%。
According to study of shock wave propagation and fragment movement after explosion of blast fragmentation warhead , a more ac-curate 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 pre-formed 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%.
