in order to improve the defense ability of reactive armor against shaped charge jet, a multi-point shaped charge structure is designed in the first layer of traditional explosive reaction armor, and the active passive combination method is used to interfere with the jet. The specific action process is as follows: after obtaining the signal of series warhead charge impacting explosive reactive armor. Take the initiative to detonate the shaped charge. Multiple damage elements are formed to interfere with the shaped charge jet actively. Based on LS-DYNA, the numerical simulation of multi-point shaped charge structure is carried out, and the charge structure and angle are optimized. The results show that the damage elements in different directions can be focused along the axial direction of the incoming jet by adjusting the charge structure. Changing the focal length of the converging jet can cause interference or fracture at different positions of the jet. The research results of this paper can provide reference for the design of active passive reactive armor.
