Abstract

For improving damage effectiveness of EFP with embedded structure, based on the AUTODYN, simulation and analysis on forming shape and velocity of EFP warheads with embedded structures containing single cylinder, double cylinders, combined cylinder and circular truncated cone were performed respectively. The results indicate that when embedded structure volume keeps constant, and structural parameters change in suitable ranges, three types of embedded structures above may influence a little on EFP velocity but significant influence on aerodynamic shape. Conclusion: the embedded structure containing combined cylinder and circular truncated cone with reasonable characteristic parameters can bring EFP with a compact structure, relatively good aspect ratio and velocity (5 and 1 788 m/s respectively obtained in this paper), reasonable aerodynamic shape.

Key words： terminal sensitive projectile; embedded structure; EFP; AUTODYN
