چکیده
This article addresses the problem that remaining useful life (RUL) prediction accuracy for a high-speed rail catenary is not accurate enough, leading to costly and time-consuming periodic planned reactive maintenance costs. A new method predicting RUL of proposed based on Bayesian optimization stacking ensemble learning method. Taking uplink downlink data railway line as an example, preprocessed historical are input into integrated model hyperparameter training, root mean square error (RMSE) final optimized result 0.068, with R-square (R2) 0.957, absolute (MAE) 0.053. The calculation example results show improved algorithm improves RMSE by 28.42%, 30.61% 32.67% when compared extreme gradient boosting (XGBoost), support vector machine (SVM) random forests (RF) algorithms, respectively. lays foundation targeted equipment system performed before fails, thus potentially saving both costs time.

Bayesian Approach for Remaining Useful Life Prediction
Prediction of the remaining useful life (RUL) of critical components is a non-trivial task for industrial applications. RUL can differ for similar components operating under the same conditions. Working with such problem, one needs to contend with many uncertainty sources such as system, model and sensory noise. To do that, proposed models should include such uncertainties and represent the bel...
متن کاملA Neural Network Approach for Remaining Useful Life Prediction Utilizing Both Failure and Suspension Histories
Artificial neural network (ANN) methods have shown great promise in achieving more accurate equipment remaining useful life prediction. However, most reported ANN methods only utilize condition monitoring data from failure histories, and ignore data obtained from suspension histories in which equipments are taken out of service before they fail. Suspension history condition monitoring data cont...
متن کاملA Bayesian Framework for Remaining Useful Life Estimation
The estimation of remaining useful life (RUL) of a faulty component is at the center of system prognostics and health management. It gives operators a potent tool in decision making by quantifying how much time is left until functionality is lost. This is especially true for aerospace systems, where unanticipated subsystem downtime may lead to catastrophic failures. RUL prediction needs to cont...
متن کاملA Study on Remaining Useful Life Prediction for Prognostic Applications
We consider the prediction algorithm and performance evaluation for prognostics and health management (PHM) problems, especially the prediction of remaining useful life (RUL) for the milling machine cutter and lithium‐ion battery. We modeled battery as a voltage source and internal resisters. By analyzing voltage change trend during discharge, we made the prediction of battery remain discharge ...
