Abstract
The utilization of wind turbines as a reliable and sustainable source of energy has gained significant attention in recent years. Within the wind turbine generator system, bearings play a crucial role in ensuring efficient operation. However, the bearings employed in wind turbines face immense challenges, including heavy loads, high speeds, and harsh environmental conditions, which can result in fatigue failure. Accurate prediction of the fatigue life of wind turbine bearings is therefore vital for ensuring the reliable and long-term performance of wind turbines. This review article provides a comprehensive overview of the fatigue failure modes observed in wind turbine bearings. It explores various load measurement techniques employed to analyze bearing loads in wind turbine systems and discusses the mathematical models utilized for predicting the fatigue life of bearings. Additionally, the paper presents an examination of experimental investigations on load measurement in wind turbine bearings and highlights the importance of data acquisition systems and software used for analyzing bearing performance. Furthermore, the review discusses the current state of research in the field and identifies potential avenues for future investigations. The significance of accurate fatigue life prediction in wind turbine bearings is emphasized, as it enables proactive maintenance strategies and enhances the overall reliability and efficiency of wind turbine systems.
