饱含液体的单胞结构对射流的干扰特性分析
Analysis of liquid-filled unit cell structure subjected to shaped charge jet impact
摘要
Abstract
Based on the virtual origin theory,the shock wave reflection theory and the jet interference theory,the theoretical model for the jet penetrating a liquid-filled unit cell structure was improved and perfected in consideration of the liquid's spray and radial convergence.The exact expression of the disturbance velocity range of the jet,the expression of the liquid's spray velocity and the expression of the liquid's flow were derived.The theoretical mode of this paper was confirmed by in the comparison of the theoretical and the experimental results of the disturbance velocity range of the jet.The results showed that the liquid's spray and radial convergence exert influence on the shaped charge jet's stability,leading to the jet's necking and fracture,thereby reducing the jet's residual velocity and residual penetration ability.关键词
