Experimental Uncertainty Analysis of Gear Fatigue Life Theoretical Prediction

Gear design is a good example of a complex engineering activity which involves knowledge of several subjects such as Application Requirements, Sizing Analysis, including Stress Analysis, Material Properties Analysis, Tribology Aspects, Manufacturing Process Capability, Prototypes Requirements, Bench Tests, Failure Analysis and Reliability Studies. All those listed subjects represent the basic elements supporting life estimation activity based on design criteria developed to avoid or define expected occurrence of specific failure mechanisms [2][3].
