摘要
The influence factors of fretting wear of bolted joints structure were carried out by using acoustic emission (AE) based on fretting wear theory, and special attention was paid on torque, acceleration and frequency of the external stimulation. Results showed that AE can characterize the degree of fretting wear of bolted joints structure. Fretting wear mainly depended on torque, and was of different sensitivity to the acceleration of the external stimulation. The other method and equipment will be needed to be adopted for the influence of the frequency of the external simulation for the further research. A new idea and a feasible on-line monitor method have been provided for fretting wear.
