RISUncertainty Quantification in the Prediction of Remaining Useful Life Considering Multiple Failure Modes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Despite the substantive literature on remaining useful life (RUL) prediction, less attention is paid to the influence of epistemic uncertainty and aleatory uncertainty in multiple failure behaviors in the accuracy of RUL. ...
Uncertainty Quantification in Fault and Degradation Analysis of Rolling Element Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents an innovative framework for deriving degradation models of rolling element bearings through uncertainty quantification. Natural open-source run-to-failure experimental datasets, XJTU-SY and PRONOSTIA, ...
Incipient Fault Point Detection Based on Multiscale Diversity Entropy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: If the incipient fault (IF) point is not corrected, it may imply a poor prognostic framework, a false value of remaining useful life (RUL), and unexpected catastrophic failure. The use of the concept of multiscale diversity ...
