Based on the high and low cycle fatigue test results of turbine attachment, the fretting fatigue damage control parameters were determined and the life prediction model was established. Parametric model of turbine attachment was established. The correlation between various damage parameters such as equivalent stress, contact pressure, friction stress, related slip distance and the fretting fatigue life was further analyzed by finite element analysis, finding that the FFD (fretting fatigue damage) parameters with integrated consideration of fatigue and wear had the highest correlation with the life, and the correlation coefficient could reach 97%. Based on the power function, the relationship between the FFD parameters and the fretting fatigue life was fitted, and the predicted fretting fatigue life of the turbine attachment was within 1.5 times scatter band. The sensitivity analysis of FFD parameters to geometric parameters was carried out, and the effects of different geometric parameters on fretting fatigue life were obtained from the perspective of numerical simulation: the fretting fatigue life was most sensitive to the pressure angle, which showed a negative correlation.
