Bumper beam, is one
of the first structures exposed to impact at the time of an accident.
Therefore, how it behaves at the time of an accident is extremely important in
terms of passenger safety, cargo and other critical parts of the vehicle. What
is expected from a bumper beam is to absorb the kinetic energy of the vehicle
through plastic deformation, particularly at low and medium speeds. In this
study, finite element models of the crash situations of the bumper beams with
five different cross-sectional geometries and equal weights were created by
using the HyperMesh software and crash analyses were carried out. Since the
bumper beams may behave differently in different barrier types, pole and wall
barrier impact test was investigated. AA6061-T6 Aluminum alloy was used as the
material and Johnson-Cook was used as the material model. The results revealed
that the cross-sectional geometry had significant effect on crashworthiness and
that the models exhibited different crashworthiness on wall and pole barriers. RADIOSS/explicit and
non-linear finite element codes were used.
