| Abstract: | Fretting fatigue usually occurs in lap joints of aircraft structure. The developing history of fretting tribology, the test technic, damage mechanism and effecting factors of fretting fatigue were introduced and reviewed. Three key technologies of fretting fatigue in lap joints of aircraft structure were analyzed, which were fretting fatigue life calculating, holistic life prediction methodology and fuzzy reliability model. |
