Micro-Mechanics Based Gear Tooth Contact Fatigue Analysis

Abstract:
Microstructure-based component life prediction (CLP) tool is validated through gear contact fatigue test and used to create contact fatigue S-N curve. Trade off study of different micro-material structures, grain size, surface roughness, and residual stress, is conducted to understand the impact on fatigue life. The results can be used as gear material design guidance to save expensive cost of fatigue test.
