“…These structures are subjected to external loads while suffering fretting damage, such as tension and compression, bending, torsion, and combined loads 2–5 . Under the combined action of fretting fatigue and fretting wear, fretting cracks will appear on the surface, which greatly reduces the fatigue limit of the structure 6–9 . Studies have shown that fretting can reduce the fatigue strength of the material by up to 50% and the life span by more than 30% 10 …”

This paper takes the dovetail structure of an aero‐engine compressor as the research object, designs a high‐temperature dovetail fretting fatigue test, and discusses the effect of high temperature on fretting fatigue damage. Based on the fretting fatigue continuous damage accumulation model, a high‐temperature fretting fatigue life prediction model of dovetail tenon considering the temperature effect is proposed and verified by experiments. The results show that the experimental data prove that the model has good prediction accuracy and its prediction error is less than 19.24%. Finally, the relative sliding distance, contact stress, Ruiz parameters, and friction work of the dovetail structure are selected, and the dovetail structure under different actual use conditions is calculated through simulation. The influence of friction coefficient, load, temperature, arc size, and other factors on the evaluation index is analyzed. The internal law of high‐temperature fretting fatigue life of dovetail structure under multi‐factor coupling conditions is studied.

This paper investigated the effect of variable normal load on the fretting fatigue mechanism. A kinetics-based Q- P curve analysis method was proposed to assist testing system design and experiment result analysis. Based on this method, a biaxial fretting fatigue testing system was designed. Experimental and numerical investigation was carried out to discuss the effect of biaxial loading phase difference (the phase difference between bulk load and cyclic normal load) and stiffness ratio (the stiffness ratio between pad fixture and flat specimen) on the fretting fatigue mechanism. Based on the critical plane approach and proposed Q- P curves analysis method, it is found that the fretting status is partial slip regime under small stiffness ratio conditions. The stress/strain which is influenced by phase difference is the main factor of fretting fatigue damage in this condition. Furthermore, the mean stress of the normal load on the critical plane is compressive stress. It directly influences the fatigue damage under partial slip regime. With the increase of stiffness ratio and phase difference (from 0° to 90°), the fretting status changes from partial slip regime to gross slip regime, which means that the influence of wear increases. Wear inhibits the initiation of fatigue cracks, which has a positive influence on fretting fatigue life. As a result, the fretting failure mode gradually changes from fatigue to wear.

The present work is aimed at establishing an engineering design method for fretting fatigue based on experimental and computational investigation of dovetail structures made of nickel‐based superalloy. Severe stress gradients and surface wear damage make fretting fatigue difficult to be assessed based on conventional fatigue life models. With the help of detailed experimental investigations and finite element computations, a fretting fatigue life model based on the nominal pressure on the dovetail contact surfaces was related to the nonlocal multiaxial fatigue analysis. The derived fretting design method based on the nominal pressure shows a life prediction distribution within the double‐scatter band and agrees with experiments fairly well. The present model provides an efficient and easy‐to‐use design method for engineering applications.
