Özet:

 


Thin-walled
structures (TWTs) are widely used in automotive and aerospace industries due to
their easy formability, high energy absorption capacity, low cost and
lightweight advantages. In this study, under dynamic axial load, the
crashworthiness of spot-welded and double-hat shaped elliptical TWT was
investigated by the finite element method (FEM). In addition, bead-shaped
trigger mechanism was added to the TWT to reduce the peak crushing force.
Changes in wall thickness (thickening or thinning of some elements), plastic
strain and work hardening may occur during forming. In order to investigate the
effect of the forming history on crashworthiness, the TWT was formed by
single-acting deep drawing using FEM and results were mapped. The results
showed that the forming history has effect on the crashworthiness of the tube.
With deep drawing results mapped to the tube, energy absorption decreased by
5.218% and peak crushing force decreased by 3.614%. RADIOSS/explicit and
nonlinear FE codes were used.
