| Abstract: | In order to improve the destructive capability of the poly energy armor breaking combatant, a cylindrical bicone combined drug mask is designed. The effects of the cylindrical diameter d, height h, upper cone angle α, and lower cone angle β on the velocity and penetration depth of the jet head are investigated by numerical simulation with the orthogonal optimization design of the mask. The results show that the upper cone angle and cylindrical diameter are the main factors affecting the jet head velocity and penetration depth, respectively. Therefore, the optimal design of the hood that takes into account the jet velocity and penetration depth is obtained in the optimization design: when d=8 mm,h=12 mm,α=36 ° and β=56 °, the velocity of the jet head is 8 667 m/s, and the penetration depth reaches 173.7 mm.The research results of the optimized design have certain practical engineering guidance significance, which can provide effective design solutions for the performance enhancement of the poly energy armor breaking combat unit. |
