An extensive review of vibration modelling of rolling element bearings with localised and extended defects

摘要: This paper presents a review of literature concerned with the vibration modelling rolling element bearings that have localised and extended defects. An overview is provided contact fatigue, which initiates subsurface surface fatigue spalling, subsequently leads to reducing useful life bearings. A described development all analytical finite (FE) models available in for predicting response Low- high-frequency signals are generated at entry exit elements into out bearing defect, respectively. The this finding along approximate these signals. Algorithms estimate size defects reviewed their limitations discussed. summary presented followed by recommendations future research.
