초록

Finite Element analysis were carried out to investigate the deformation behaviours of a buckled automotive seat frames made of three different types of materials, i.e., SAPH440, Al6082-T6 and Al7021-T7, when they were subject to external load, based on the ECE R14 regulation to achieve lightweight structure. Also, several thicknesses were applied to the seat frame structures of each material for characterising deformations. It was found that light weight seat frame structure was obtained compared to conventional steel structure when it was made of aluminium under the condition of satisfying ECE R14 regulation. Interpretation result, when changing from SAPHH440 material has a thickness of 1.5mm to Al material has a thickness of 3.0mm, that could checking weight lightening about 47%.
