Through a review of relevant domestic and international literatures on fretting fatigue research， this paper first introduces the concept and characteristics of fretting fatigue. It summarizes the current research status regarding the mechanisms of fretting map theory and investigations into the microscopic mechanisms of fretting fatigue. Secondly， the main factors influencing fretting fatigue life prediction are summarized， including relative slip amplitude， contact pressure， axial load， coefficient of friction， stress gradient， and temperature. Finally， the widely studied and employed methods for predicting fretting fatigue life are comprehensively reviewed. The development trends in fretting fatigue life prediction and future research prospects are summarized. Considering the wear-fatigue coupling damage mechanism and artificial intelligence （AI）-based fretting fatigue life prediction methods are identified as current research hotspots and represent key directions for future development.
