This study introduces two deep learning models for predicting bearing remaining useful life (RUL). These models, TSMC-CNN and TSMC-CNN-ALSTM, offer accurate end-to-end RUL prediction from raw data.

Area of Science:

  • Engineering
  • Computer Science
  • Machine Learning

Background:

  • Accurate prediction of remaining useful life (RUL) is crucial for predictive maintenance in machinery.
  • Traditional methods often require extensive feature engineering and may not capture complex temporal dependencies.

Purpose of the Study:

  • To propose novel deep learning architectures for end-to-end RUL prediction of bearings.
  • To enhance RUL prediction accuracy by leveraging multi-channel time series analysis and attention mechanisms.

Main Methods:

  • Developed Time Series Multiple Channel Convolutional Neural Network (TSMC-CNN) for feature extraction from multi-channel time series.
  • Integrated an attention-based Long Short-Term Memory (ALSTM) network with TSMC-CNN (TSMC-CNN-ALSTM) to focus on relevant temporal features.

  • Main Results:

    • Both TSMC-CNN and TSMC-CNN-ALSTM demonstrated superior performance in RUL prediction compared to existing methods.
    • The proposed models achieved lower Mean Absolute Error (MAE) and Root Mean Squared Error (RMSE).

    Conclusions:

    • The proposed end-to-end deep learning methods effectively predict bearing RUL.
    • TSMC-CNN-ALSTM, incorporating an attention mechanism, offers enhanced accuracy for RUL prediction tasks.
