近自由液面聚能战斗部水下爆炸威力场
Underwater Explosion Power Field of Near-Free Surface Shaped Charge Warhead
摘要
Abstract
In this paper,a damage test of the shaped charge warhead to underwater target plate is carried out,and the corresponding numerical simulation model is developed.The whole process of jet formation and damage plate is simulated by arbitrary Lagrange-Euler(ALE)algorithm,and the effectiveness of the algorithm is also verified.Then,the characteristics of shock wave and metal jet of the small cone angle shaped charge warhead in near free surface explosion are studied by a range of examples.The results show that the underwater explosion pressure of the shaped charge warhead is asymmetric.The free surface has no obvious effect on the metal jet.However,under the influence of the sparse wave reflected at the free surface,the pressure of shock wave near the free surface decreases and the cavitation area appears.关键词
