Abstract
In this study, structural analysis for the seat frame of automotive was carried out using finite-element analysis (FEA) technique and comparative analysis of the designs of lightening method, while not degrading the strength and stability of the frame. Maximum equivalent stress and maximum deformation amount on the whole seat frame were analyzed by employing the loading condition of passengers on the back and cushion frames, which were made of steel as in the current seat frame of automotive. Moreover, an additional structural analysis of a seat frame that is made of carbon fiber reinforced plastic (CFRP), instead of the currently using steel material, was performed. The result of this analysis showed that the maximum displacement is increased when using CFRP, instead of steel. In addition, the lower density property of CFRP materials has the potential to reduce the weight of the frame when compared with that of the steel material. Therefore, this result suggests that the steel material that is being currently used in most automotive must be reduced. Overall, this study identifies the structural safety of the seat frame of automotive by comparing the distributed strength of different materials.
