| Abstract: | There exists considerable motivation to
reduce vehicle weight through the adoption of lightweight materials, such as
aluminum alloys, while maintaining energy absorption and component integrity
under crash conditions. This paper reports the deformation and damage behaviors
of under crushing loadings with circular and square cross-sections so that,
circular and square columns have used same material. The numerical analysis is
carried out by Abaqus software. Subsequently, the collapse behavior of aluminum
extrusion damage is validated by comparing against solution published in
literature. Finally in order to find more efficient and lighter crush absorber
and achieving minimum peak crushing force, response surface methodology (RSM)
has been applied for optimizing the aluminum extrusion column. After obtaining
the optimal designs, parametric studies are performed to investigate the
influences of the design variables on the crash performance of such
thin-walled columns. |
