Simulation on Formation Process of Penetrator With Double Layer Liners
摘要
Abstract
To find a numerical method to study the formation process of tandem penetrators and penetration process,the formation of shaped charge with double layer liners(SCDLL) affected by detonation products was studied by using AUTODYN hydrocode. The simulation was conducted to compare the effect of the following solution techniques on the prediction of velocity and shaped of EFP:Lagrangian,Eulerian-Lagrangian Coupling and Eulerian. The shaped charge composed of one explosive and two liners ignited at the center point was studied. The simulation results were compared with the experimental X-ray pictures. The results show that, the simulation adopting Lagrangian resolution agrees well with the experimental results when Lagrangian resolution is adopted and the friction coefficient between two liners is 0.28.关键词
