Abstract :
Fretting fatigue is a phenomenon which occurs when two parts are contacted to each other and one of those parts or both are subjected to cyclic load. Fretting decreases fatigue life of materials drastically. Therefore Investigation of fretting fatigue life of materials is an important subject. In this work the fretting fatigue life of AL7075-T6 alloy has been investigated by conducting a series of rotary bending fatigue tests at 50 Hz. A fuzzy logic model was offered to predict the fretting fatigue life of AL7075-T6 with respect to changes in input process parameters, friction pads pressure and bending stress amplitude. Two membership functions are allocated to be connected with each input of the model. The predicted results achieved via fuzzy logic model were compared to the experimental result. The result demonstrated an arrangement between the fuzzy model and experimental results with the 94.72% accuracy.
