| 摘 要： | 通过有限元显式动力分析程序的显式算法,对石油射孔弹顺序起爆后弹间爆轰冲击波干扰的过程进行了2维数值模拟,并考虑了弹体对弹间干扰的影响,对模拟结果进行了讨论；分析了影响高孔密射孔技术的弹间干扰产生的原因,主要是爆轰冲击波的压力场受到不同程度的干扰,致使初始爆轰波形破坏.计算结果与已有的物理现象和规律吻合,说明该计算模型和...

| Abstract: | Two-dimensional numerical simulation of detonation wave interference among perforating bullets was made by employing the explicit dynamic finite element program.Effects of the projectile body on detonation wave interference among perforating bullets were considered.And the results of numerical simulation were discussed.The main cause of interference among charges,which affected perforation result in high shot density perforating technology,was the interfered pressure field of blast wave and damaged detonati... |
