摘要

The lethality of the circumferential direction fragment field of the warhead has improved greatly due to the premade fragment technique, but the axial fragments are still too few to block the battle space completely. Aiming to improve the distribution of the axial fragment field of the warhead and explore the factors influencing the velocity and scattering angle of the axial premade fragments, we designed an axial forward enhanced warhead by changing the shape and curvature of its head, and displacing the premade fragment to the head of the warhead to improve its lethality in the axial direction. We simulated the whole explosive driven process using LS-DYNA, the influence of the warhead structure on the velocity, and obtained the scattering angle of the axial premade fragments by setting different initial conditions. The results show that the velocity and the scattering angle of the axial premade fragments were closely related with the warhead structure. In addition, when the arc-shaped head warhead was adopted, the velocity, scattering angle, blocking area, and the lethality of the premade fragments were all significantly ameliorated.
