In this study, the analyses of structure, fatigue and vibration with two models of 1 and 2. As the result of structural analysis, the equivalent stress and the total deforamtion of model 1 become higher than those of model 2.Model 1 shows fatigue life more than model 2. As the vibration analysis, model 1 has the safety better than model 2. As shown by these results, the main parts ofdamage and the weak areas can be investigated to differ from each other according to the configuration of model though these models have the same material property. The result of this study through the analysis can be applied to develop the optimal design of automotive seat frame with durabilty and safety.
