Experimental Study on IPM for Buffering and Energy Absorption

doi:10.12382/bgxb.2023.0422

Abstract

Abstract:

In order to ensure the reliability of hard target penetration fuze in the battlefield, an imitation bamboo type penetration fuze protection microstructure (IPM) is designed based on bionics principle. A dynamic model of fuze buffering system is derived based on the buffering and energy absorption mechanism. The Abaqus explicit dynamic finite element method is used to numerically simulate the mechanical properties of IPM and traditional straight edge structure under typical penetration conditions, and the buffering protection performances and compressive mechanisms of the two structures are compared and analyzed. Two structures made of metal materials (AlSi10Mg and GH4169) are prepared using the selective laser melting (SLM) 3D printing. The compressive strength and energy absorption characteristics of different cell geometries are investigated, and the reliability of the established finite element model is verified. The simulated results show that IPM has obvious negative Poisson's ratio effect and deformation integrity, which can eliminate stress concentration and attenuate the peak value of penetration overload by 131% on average. The 3D printing results show that GH4169 has better molding effect, complete features, and high structural strength, making it more suitable as a printing material for fine structures. The quasi-static compression results indicate that the initial yield stress of IPM is higher than that of traditional straight edge structure, showing a significant advantage in the platform area, and its total energy absorption is 72% higher than that of traditional straight edge structure. The results of this study provide a new strategy for the protection of hard target penetration fuzes.
