Dynamic modelling of deep groove ball bearings with different local defects considering skidding and thermal elastohydrodynamic lubrication

Abstract: The vibration characteristics and skidding behaviour of deep groove ball bearings (DGBBs) are significantly influenced by the evolution of local defects and thermal effects. In previous studies, the influences of skidding and thermal effects were not considered in order to simplify the model of defective bearings. But the presence of skidding and thermal should not be ignored to accurately simulate the operation of bearing. To gain a comprehensive understanding of the operational mechanism of defective bearing… Show more

“…Luo et al [10] proposed a four degrees-of-freedom dynamic model of a rolling bearing to analyze the influence of inner and outer raceway compound defects on the vibration response of the rolling bearing. Tian et al [11] developed a dynamic model for defective deep-groove ball bearings to investigate the vibration response and skidding behavior associated with seven types of faults. Therefore, it is helpful for an effective diagnostic technique to enhance the fault's periodic impulses and eliminate noise interference [12].…”

“…The investigation of rolling element fault diagnosis has its origins in the construction of vibration models for faults in rolling bearings [5]. The academics developed a dynamic model for defects in single rolling elements and explored the impact of rolling element faults on the vibration response of bearings [6][7][8]. The inherent mechanism of multi-rolling element faults is intricate, bringing the establishment of precise dynamic models challenging.…”
