NUMERICAL SIMULATION ON THE INTERFERENCE WITH ROD PENETRATOR BY LINEAR SHAPED CHARGE

At present,the shaped explosive reactive armor,which is the most advanced and has three functions of defence,is a new type of reactive armor.Among them,the linear shaped charge with large cone angle is the most important part in the design of this type of reactive armor,and it is mainly used to intercept incoming high-speed rod penetrators.The process of the linear SFF interfering the rod penetrators was studied with ANASYS/LS-DYNA numerical simulation method.It was specifically and thoroughly analyzed that the process of SFF forming,the process of linear SFF interfering the rod penetrators and the process of rod penetrators penetrating the aftereffect target,and two main reasons of the decline of armor-piercing power since the rod penetrators had been interfered by the linear SFF were reached.Through comparing with experiments,it was obtained that the results of numerical simulation were basically consistent with them.
