摘要：A high-temperature fretting fatigue life prediction model based on continuum damage mechanics (CDM) was developed to predict the fretting fatigue life of the aero engine dovetail joint structure at different temperatures. Considering the complex influence of temperature on the fretting fatigue, the temperature dependent damage rate factor was introduced in the fretting fatigue life prediction model based on non-linear continuous damage (NLCD) model. The model was used to predict the fretting fatigue life of titanium alloy TC11 dovetail joint structure of an engine simulated samples at different temperatures. Compared with the test results, the life predictions were within 2 times of the error range, proving the validity of the life prediction model. © 2019, Editorial Department of Journal of Aerospace Power.
