Abstract

As a kind of porous material, aluminum honeycomb is widely used in the field of energy absorption. In this paper, the mechanical properties of aluminum honeycomb under different impact angles are analyzed. The results show that the peak collapsing force is largest in the axial impact, and it is significantly reduced in the oblique impact. When the impact angle is small, the platform force and energy absorption of aluminum honeycomb are less affected. When the impact angle increases to a certain value, the aluminum honeycomb will buckle as a whole, and the platform force and energy absorption will be significantly reduced. When the impact angle continues to increase to a specific value, the aluminum honeycomb will be tilted as a whole, and the platform force and energy absorption will be significantly reduced. This study has reference significance for the design of aluminum honeycomb buffer device.
