Due to the lack of low cycle fatigue (LCF) parameter data of remanufactured turbine disk on aeroengine, it is impossible to predict the low cycle fatigue life of remanufactured turbine disk directly by using traditional life prediction method. Considering the relationship between fatigue limit and fatigue life, the life corrective factor of remanufactured turbine disk is put forward to correct the life prediction results obtained by finite element stress-strain analysis and local stress-strain method, then the life of remanufactured turbine disk is predicted. Finally, the prediction results are compared with the relevant experimental results, which proves that the prediction results are accurate.
