The work aims to study the process of axial compression deformation and energy absorption characteristics of aluminum honeycomb structure with the minimum periodic structure of aluminum honeycomb—"Y" shaped cell, base on the important influence of adhesive strength on the energy absorption characteristics of aluminum honeycomb, so as to know about the influence of different adhesives on the energy absorption characteristics of aluminum honeycomb. The Von Mises constitutive model was used to characterize the mechanical properties of adhesives. A "Y"-shaped finite element model with adhesive layer was established to simulate the crush deformation process of aluminum honeycomb structure, and the deformation and failure phenomena of adhesive layer were obtained. As different adhesives had different failure situations, the average compression strength and energy absorption value of the corresponding “Y” shaped cell would be different. The model could effectively simulate the crush deformation process of aluminum honeycomb structure and predict the deformation and failure of the adhesive layer accurately. The calculation accuracy of the finite element model of “Y” shaped cell established through experimental verification could meet the needs of practical engineering. Through the quasi-static crushing finite element simulation on the “Y” shaped cell, the suitable adhesive is selected for the production of aluminum honeycomb and the foundation is laid for the further research on the subsequent package buffers.
