| Summary: | The current study examines the energy
absorber capacities of the aluminum alloy AA6060
material in frontal longitudinal members of the
crashworthiness applications. The aluminum alloy is
subject of various studies because of its lighter weight,
which helps to decrease the fuel consumption, and to
protect the environment. The simulations are based on
the non-linear finite element (ABAQUC CAD 6.10).
The thin walled rectangular tube, enhanced by trigger
mechanism, was subjected to direct loading. Elliptical,
square, and circular trigger geometries were combined
with different trigger positions and reductions. The
best achieved result was the energy absorption
enhanced by 16.2%, and the CFE enhanced by 16%,
which results contributes to the safety of the
passengers. This outcome has been given by the
elliptical trigger situated at the distance of 50 mm from
the free end of the tube with 10% reduction. |
