Reliability Analysis of Rolling Bearings Using a Weighted Nonlinear Mixed-Effects Degradation Model
Reliability assessment of rolling element bearings is critical for the predictive maintenance of industrial rotary machinery.This study proposes a Quadratic-Exponential Weighted Model (QEWM) based on Nonlinear Mixed-Effects (NLME) to characterize the degradation process of bearings. Utilizing the IMS Bearing Dataset (S...
