Heterogeneous Feature Models and Feature Selection Applied to Bearing Fault Diagnosis (2015, methodology): “Considering the final attribution of the vibration pattern to a machine condition, it can be observed that no classifier at all is used in [5], [12], [13], and [18]; only the visual inspection of peaks in frequency graphs suggests the discriminative power of the method.”
An improved analytical model for a lubricated roller bearing including a localized defect with different edge shapes (2018, methodology): “The impacting force Fsd caused by the LOD includes the static and dynamic impacting forces (Sassi et al., 2007), which is given by Fsd ¼ Fst þ Fdy ð42Þ where Fst is the static impacting force, which is calculated by Fst ¼ Qmax 1 1 cos ’i 2" 10=9 ð43Þ where Qmax is the maximum load for the rollers,…”
An extensive review of vibration modelling of rolling element bearings with localised and extended defects (2015, methodology): “262 The common feature of all models in references [53–69], except the models in references [66, 67], is that 263”
Analysis of bearing stiffness variations, contact forces and vibrations in radially loaded double row rolling element bearings with raceway defects (2015, background): “Damping is included either locally in the contacts between the rolling elements and raceways [25, 26], or globally by attaching a grounded damper to the inner raceway [21–24, 27, 28].”
