摘要：

The fretting-fatigue behaviour of shrink fit lug-bush assemblies is investigated. In this paper, experimental fa-tigue tests are carried out on lug-bush specimens with three different levels of interference fit. It is observed that the relative movements of fretting induce tribo-oxidation phenomena at the shrink-fit interface and that the crack initiation sites correspond well to the oxides formation spots. The increase in the fatigue life with interference fit is consistent with stress analysis considering the SWT multiaxial fatigue criterion, but the predicted fatigue life is not conservative relative to material reference data. In order to account for fretting surface damage, different approaches are investigated considering homogeneous and heterogeneous distributions of the coefficient of friction.
