摘要
针对K装药结构,基于改进的射流成型理论,建立了K装药射流形成与侵彻理论模型,并通过Mathematica软件编程计算射流成型过程。结果表明:相对于传统锥形罩装药,同样药型罩结构的K装药形成射流的头部速度提高了31.02%,质量堆积点降低了23.8%,射流长度增加了30.5%。优化设计适用于K装药的偏心亚半球型药型罩,形成了速度较高、质量比大、质量堆积点降低且更易拉长的杆式射流,并进行了静爆试验验证,理论计算与试验的侵彻深度结果误差为5.8%。
Aiming at K-charge, the theoretical model of K-charged jet generation and penetration was built based on the improved theory of jet, and the program was writen by Mathematica to calculate the K- charged jet forming. In comparison with the traditional cone-type liner, K-charge with the same liner can add the head speed of jet by 30. 02%,and the mass accumulation point reduces by 23. 8% and the jet length increases by 30. 5%. The eccentric hemisphere K-charge was optimized and designed. The rodshaped jet forms, which has high speed, large mass ratio. The mass accumulation point of the jet advances. The static detonation experiment was carried out. Compared with the experiment results, the penetration-depth error of the theory is only 5.8%.
