    Modified Three-Parameter Model to Predict Compressor Blade Fatigue Life under Vibration Loading

    Modified Three-Parameter Model to Predict Compressor Blade Fatigue Life under Vibration Loading


    This paper investigates steel alloy stator blade flexural vibration characteristics and fatigue properties analytically using flexural fatigue tests. First, fatigue life data reliability is analyzed and theoretical strain endurance limit Δ ε C deficiencies are assessed. A model from the literature is used to predict fatigue life using fatigue test data for four steel alloys to derive an extended estimation expression for the strain endurance limit. The proposed three-parameter fatigue life models can be applied to estimate steel alloy blade fatigue life in practical working environments.
