abstract

It is well known that cellular metal is an ideal structure used in transportation passive safety field for its low density and high energy absorption capacity. In this paper, a kind of regular cellular metal based on cubic structure is proposed. The cubic cells are manufactured through sheet metal stamping process. Then the cells could be bonded together by adhesive to form the cellular structure. The compressive properties of the cellular metal are studied by experiments. The dynamic behaviors are studied by numerical simulations. To distinguish the individual and interactive effects on the energy absorption capacity, a full factorial Design of Experiment with sixteen configurations is carried out based on the four parameters that are essential to the design of cellular metal. The effects of impact velocity on crushing deformation are analyzed. It has been shown that the regular cellular metal based on cubic structure will have a wide application in industry.
