Remaining useful life prediction for rolling bearings based on RVM-Hausdorff distance

Peihua Xu,

et al.

Abstract: To address the shortcomings of existing bearing remaining useful life (RUL) prediction process such as low accuracy and reliance on expert experience for parameter estimation, this paper proposes a bearing RUL prediction method combining relevance vector machine (RVM) and hybrid degradation model. The bearing degradation characteristics are extracted from the acquired vibration acceleration signals, the time-varying $3\sigma$ criterion is then used to determine the bearing first predicting time (FPT), and the … Show more

“…These factors comprehensively affect the health status of bearings, making RUL prediction a challenging task [2]. Typically, methods for predicting bearing RUL include model-based [3]- [6], data-driven, and hybrid approaches [7]- [10]. Compared to model-based methods, data-driven approaches can learn degradation patterns from sensor signals and establish predictive models through machine learning or deep learning.…”
