An accelerated life test(ALT) is a test method that forces components to fail more quickly than they would under use condition by applying higher overstresses. When 2 or more accelerating stresses are involved in ALT, the interaction effect may occur. The life data obtained are extrapolated using a life-stress relationship to estimate the life distribution at a use condition. We use the general log-linear relationship to model the dependence of life of the Weibull distribution on stress. Therefore, this study suggests the acceleration factor model between the lives at use condition and accelerated condition by using pneumatic cylinder life data considering an interaction effect.
