This paper mainly conducts numerical simulation and analysis of the warhead structure of 80 mm assault ammunition, which needs to realize the effective penetration of 400 mm into the C35 concrete target and carry out the killing of incoming bullets. Before the first level of warhead design: effective penetration level before the warheads main function is to 400 mm C35 concrete goals, to achieve tactical technique index by shaped charge, bar type jet formation, medicine type cover adopt ball is short of cover, material is copper, medicine cover type choose such as wall thickness, and wall thickness of 2.52 mm, dynamite to choose B, using Ls-Dyna software simulation. The results show that the structure design has good jet forming, which can easily penetrate the 400 mm C35 concrete target plate, and the opening diameter is more than 20 mm. Through the hole opening diameter of the front rank warhead, it is finally determined that the diameter of the incoming bullet is 20 mm and the killing force is effective.
