摘 要：1
Abstract: Combining the optimization and FEM technology, crashworthiness of aluminum extrusions was studied for an automobile safety plan. The effects of longitudinal stiffeners on the crushing of stiffened square columns were studied considering the damage evolution. The numerical analysis was carried out by Abaqus software. Subsequently, the collapse behavior of aluminum extrusion damage was 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 tube.
