Summary: This paper proposes an adaptive nonlinear Wiener process model to predict the remaining useful life (RUL) of rolling bearings, using the closed skew-normal (CSN) distribution to model the non-normal and asymmetrical degradation characteristic in inter-product variation. An online recursive algorithm based on Bayes' theorem is derived to update the hidden drift distribution, and a Bayesian smoother based on CSN distribution is developed to estimate model parameters and derive an analytical expression of the RUL distribution.

Summary: In this paper, a nonlinear dynamic model of a cylindrical roller bearing considering the dynamic contact relationship between the rollers, the raceways, and the cage is established. The variation of cage motion characteristics and its internal mechanism under different speed fluctuations are discussed, and the effects of acceleration, deceleration, amplitude, and period of fluctuation on cage stability are analyzed. The results show that the cage's unstable motion mainly occurs at the initial stage of acceleration and the later stage of deceleration. Appropriate increases in acceleration and deceleration can improve the stability of the cage movement, while excessive speed fluctuations should be avoided.

Summary: A novel method is proposed in this paper for complex-system remaining useful life (RUL) prediction based on multimodal degradation features and adjusted cosine similarity (ACS). The method employs complete ensemble empirical mode decomposition to decouple global degradation and random fluctuations, and utilizes slow feature analysis to obtain local degradation features and residual terms as global degradation features. The multimodal degradation features are transformed into one-dimensional health degradation indicators using a bidirectional gated recurrent unit autoencoder. An ACS is developed to estimate the matching similarity between the test degradation curve and the training degradation curve.
