Abstract

Recently developed automotive components are getting lighter providing a higher fuel efficiency and performance. In this research, the shape of upper control arm was determined by applying the optimization technology. This study considers the static strength in the optimization process. In this study, the kriging interpolation method is adopted to obtain the minimum weight satisfying the static strength constraint. Optimum design of static strength is obtained by the in-house program. MSC.fatigure is used for assessment of the durability life, which is one of the most important criteria in automotive industry. In addition, the real experiments on 1/4 car is conducted to validate the FEM analysis. At last, the correlation of each case about durability life is obtained.
