Aimed at the dual requirements of large hole diameter and deep penetration depth of the bunker blaster warhead and taking into account the aperture, an orthogonal optimization scheme was designed based on the 80mm caliber charge platform, and the finite element software AUTODYN was used to carry out Euler-2D numerical simulation, and The influence of the bunker blaster warhead drug cover and the baffle structure parameters on the formation of the jet and the penetration of the concrete target plate was studied. The penetration depth L and the dimensionless number γ are proposed as evaluation indicators, and the primary and secondary order of the influence of each structural parameter on the two indicators was found, and the wall thickness of the medicine type cover, the top height of the cover, the thickness of the partition, the thickness of the partition are obtained. Based on the optimal combination of diameter and so on, the static test of the reinforced concrete target is carried out. The results show that the numerical simulation is in good agreement with the test, and the penetration performance after optimization is significantly improved.
