In order to obtain the optimal super shaped charge structure, the orthogonal analysis and back propagation (BP) neural network were used to optimize the jet formation parameters of the truncated super shaped charge, and the main factors affecting the penetration power of the truncated super shaped charge were identified. The results show that when the cone angle of super shaped charge structure is 36°, the radius of additional device is 14 mm, the width of additional device is 5 mm, and the thickness of liner is 1 mm, the numerical simulation effect of jet penetrating steel plate is the best, and the depth of jet penetrating steel plate reaches 206. 4 mm.
