Abstract
On the basis of the interaction of the plate charge with the shaped jet and in view of the greater penetration capability required for the large caliber plate's more concentrated charge,this article contrasts and compares the shaped jet interference capability of the single plate charge,the double parallel plate charge and the multi-layer parallel plate charge using theoretical analysis and numerical simulation.It was found that the shaped jet interference capability of the plate charge is greater with the increase of the plate layers.The distance between the plate charges determines not only the jet interference capability but also the size of the reactive armor.The article represented the process of the interaction between the plate charge and the shaped jet using the ANSYS/LS-DYNA 3D software,and compared the residual velocity,the residual energy and the after effect of the shaped jet at some point and obtained the optimum distance (δ=25 mm)between the plate charges,thereby not only ensuring the interference effect of the multi-layer parallel plate charge on the shaped jet but also effectively controlling the size and the weight of the reactive armor.The results can serve as reference for development of new reactive armors.关键词
