Abstract: |
By using finite element software Autodyn, numerical simulation of jet forming and penetration performance of the cylinder cone liner under explosion load is carried out. The size effects of the diameter and length of the cylindrical liner are analyzed, and the parameters of jet velocity, effective length, penetration depth and perforation diameter are obtained. The results show that the jet with higher head speed and stronger penetration ability can be formed by the cylinder cone liner. The jet velocity is 8 110 m/s with the increase of the diameter and length of the cylinder. When the diameter of the cylinder is 30 mm and the length is 20 mm, the shaped charge can completely penetrate the steel target with thickness of 550 mm at the most advantageous standoff. |
