Abstract

Abstract

In this work we improved the explosion shock wave mitigation capability of the interruption structure in the tandem cutting warhead and matched the front shaped charge with the post-stage projectile and the explosive interruption by installing the explosive interruption structure between the front cutter and the rear following projectile, and established the simulation model using ANSYS/LS-DYNA, a finite element analysis software. We also analyzed the mitigation capabilities of the structures in different combinations and compared their explosive interruption capabilities using numerical simulation. The results showed that the explosion shock wave first converged to the inner region of the projectile, rather than to the tip of the warhead, so that the tip area of the outer metal flameproof medium was thinned properly. When the outer metal turned from hard steel to aluminum, little change was observed in the stress peak value of the rear end shell, suggesting that the outer metal medium was aluminum. Judging by the comparative study, the aluminum polyurea flameproof capability was superior to the aluminum foam-aluminum structure. Finally, the "soft" explosive interruption medium was determined to be polyurea, and the best explosion proof parameters were determined by adjusting the thickness of the aluminum and polyurea layer, which serves the needs of practical applications.
