Abstract

Abstract: Buffering protect of fuze under high-speed impact was realized using aluminum foam gasket with special pore structure, and numerical simulation method to achieve the buffer validity analysis. Numerical model of three-layered concrete target projectile penetration was established, and the numerical model was validated to be accurate by comparing the fuze acceleration curves of simulation and experiment results. Numerical simulations were completed to predict the cushioning effect for different foamed aluminum structures. The result reveals that foamed aluminum cushioning can reduce the load of the fuze, and the foam's void ratio and thickness will significantly affect the cushioning performance, and exits a best design value to achieve the highest efficiency. Furthermore, the foamed aluminum sandwich structure has a better cushioning performance than monolayer foam, their special structure can effectively weaken or avoid the problem which single-layer aluminum foam may easily lose protect function due to compaction. The research results can provide design reference for fuze especially buffer structure.
