Abstract
Abstract. Thin-walled tubes are widely used as energy absorption
devices for their low cost and high manufacturability. Introduction of the
origami technique enables the tube to follow a pre-determined failure mode
and to improve its energy absorption efficiency. This paper examines the
energy absorption characteristics of the origami crash box under
quasi-static axial crushing. Both experimental and numerical results show
that the origami pattern develops a diamond-shaped mode, bringing a
reduction in initial peak force and a significant increase in energy
absorption compared to the conventional hexagonal tube. The sensitivity of
its energy absorption performance to various parameters is studied, and it
is shown to achieve 68.29 % increase in the specific energy absorption and
13.91 % reduction in the initial peak force in the optimal case.
Furthermore, an analytical solution is presented for the energy absorption,
which achieves reasonable agreement with the numerical results.
