- W4387039791 abstract "Fatigue spalling of aeroengine bearings seriously affects the safety and stability of an aircraft. The existing technology of bearing fatigue spalling fault evolution analysis and life prediction is lacking. Once cracks occur, they need to be replaced and maintained, which wastes the life performance of the bearing to a certain extent. This paper conducted the fatigue spalling fault evolution analysis and life prediction of a 7208AC angular contact ball bearing's outer raceway. The finite element-based fatigue spalling fault evolution of the bearing is modeled, whose inputs contain the contacting parameters of the bearing calculated by a quasi-static model with the consideration of temperature and lubrication. The proposed method enables the analysis of the fatigue spalling fault evolution process in bearings. The analysis results are consistent with the general rule of bearing spalling. The proposed method can provide a new idea for the fatigue spalling fault evolution analysis and life prediction, and provide an important basis for aircraft emergency decision-making." @default.
