Abstract EN
This paper presents a new perception in evaluating fretting fatigue damage nucleation and propagation lifetime under periodically forced circulation.
A new approach, which is proposed in this paper, is to measure the change of the central point of power spectral density (CP-PSD) in different structural stiffness degradation stages.
A notable aspect of this study lies in the combination between vibration amplitude and forced frequency of the fatigue-causing factors in beam structures.
Additionally, it is found that randomization of the first phase from 0 to 2π yields more accurate modelling of the fatigue phenomenon.
Results show that the CP-PSD parameter is significantly more sensitive compared to the regularly damage-evaluating parameters such as natural frequency, eigenvalues, or stress value.
This reflects different levels of fatigue cycle effect on the structure in the experiment.
At the same time, CP-PSD also categorizes the degradation level on different points on the structure under the periodically forced circulation.
In addition, this paper also quantifies the relation between the changes of CP-PSD and each fatigue state.
Results of this research will be a reference source to evaluate the lifespan of the structure by experimental methods.
