Abstract
In this research, an original design of an impact absorber made of a metallic tube
with an inner honeycomb-shaped part made of a glass-fiber reinforced polyamide
is analyzed. For this task, we have employed the explicit module of the finite
element code ABAQUS. The aim is to assess the crashworthiness response of this
complete specimen, varying different parameters. For the honeycomb, cell size and
wall thickness are the two factors that are changed; whereas only the wall thickness
in the metallic tube is variable. The honeycomb height can also be modified, being
always equal or smaller than the height of the metallic tube. Two functions are
selected as metrics to evaluate the performance of the designs. These functions are
the specific energy absorption of the specimen (SEA) and the peak load (Ppeak)
produced during the crushing of the part. We have obtained quality results which
allow a deep understanding of the crash performance of the absorber.
Keywords: Crashworthiness, impact absorbers, honeycomb structure, glass fiber,
