Abstract

Aluminum honeycomb structure with special structural and functional properties, which has been widely used as energy-absorbers. To design multi-level aluminum honeycomb buffer structures better and provide theoretical basis on designing space landing module energy-absorber structures, this paper presents numerical and experimental studies on series aluminum honeycomb structures with quasi-static load. The numerical models used here with various length and foil thickness of honeycomb cell, Patran parameters design language (PCL) provides convenience to automatically accommodate the parametrized FE model to different designs. Through investigated on experiments and theoretical analysis, the numerical model can obtain plate stress and limited strain and show loads subjected on aluminum honeycomb during the whole deformation process accurate. Numerical simulation has the advantage of low cost and high precision compared with experiments. Results from numerical simulations and experiments show that series honeycomb structures can absorb more energy than single honeycomb structure.
