In order to obtain the explosive reaction armor with better interference capability to jet, a king of wedge-shaped multi-sandwich explosive reaction armor was designed on the basis of the existing wedge-shaped and flat structure explosion reaction armor. ANSYS/LSDYNA was used to simulate the interference process of the wedge-shaped multi-sandwich reaction armor on jet. Focusing on the research on the interference effects of four kinds of explosive reactive armors on jet penetration at 0° and 68°, it is found that one of the new explosive reactive armors has better jet interference effect than the other three explosive reactive armors at the impact angle of 0°. And the new explosive reactive armor is obviously best than other explosive reaction armors when jet penetrate at an angle of 68°. Finally, the relationship between the interference effect of explosive reactive armors on jet and the penetration angle of the jet was studied.
