Abstract

Abstract

To improve the axial lethality of focusing fragment warhead, we carried out a research on the axial dispersing characteristics of prefabricated fragments.Based on the Shapiro formula theory, we designed the shell and improved the charge structure of warhead, and simulated its explosion process using the LS-DYNA software and ALE algorithm.Considering the axial distribution of fragments on the target, we analyzed the relationship between the charge structure, the shell curvature and the dispersing characteristics of fragments.The results indicate that the scattering of the fragments can be controlled effectively by deferring the curvature of the shell and using the "I"-shaped charge structure.Our work has been proved to benefit researches on the control and application of the fragments scattering of warhead.
