Life prediction and reliability analysis of a cam roller system were investigated. From the tribological analysis, the cam roller system was found to operate under low film parameter conditions and components were subjected to the risk of contact fatigue. Surface analysis performed on the failed rollers indicated that the surface distress was the primary cause for failure. Then, numerical analyses were performed to evaluate the cam roller life and its related reliability. The adopted approach combined a contact fatigue crack growth calculations with a probabilistic model for controlling the design uncertainty. The computation-efficient Fast Probabilistic Integration (FPI™) code was used to solve the problem. With appropriate descriptions for uncertainty distributions, the surface fatigue life of the specified cam roller system can be predicted along with a confident reliability level. Sensitivity analysis of design parameters was also performed, and the degree of influence of each design parameter was prioritized. Results indicated that surface roughness was the most critical parameter for the cam roller system investigated.
