RUL test bed construction

- Slewing bearings can rotate at low and high speeds

- Accelerated life testing under extreme load conditions

Data analysis : Bearing fault modes

- Implementation of representative failure modes using SKF reports

- STFT is better for failure mode analysis than the traditional EEMD

Remaining useful life(RUL) estimaion algorithm

- Establishment of an LSTM-attention based model to predict RUL of entirely different systems using system HI
