Requirement terms in the development of automobile Part are progressed about light weight damage prevention by fatigue, and safety of product. Already, The before study was gained suitably the good result about light weight in the expected period of this time when they changed the metal of lower control arm. But in the case of automobile part, it was concerned with life of people. and in the result, the fatigue life is very important. In this requirement, when we: drive a car, our car is applied to the cycle load. Estimation of the fatigue properties must have respect to the design process. Estimation of the fatigue life by using the design of experiments give occasion to the decrease effect of the automobile part development time. In these days of rapidly growth, This new process is help to competition ability of automobile industry and this study will bring forth a large safety property and last development effect. finally, we wish to bring forth the one example about the fatigue life optimization of lower control arm.
