This dataset is a subset of the bearing run-to-failure dataset of UNSW :
- Horizontal acceleration (accH) measurements
- Test 1 and Test 3 from the original dataset
- Sampling frequency: 51200 Hz
- Each sample contains signal data, signal length, sampling frequency, speed (6.0 Hz), radial load (10.5 kN), defect size (1.0 and 0.5 mm), and defect type (BPFO)
Implementation
This dataset is used as the validation dataset in this RUL prediction project: https://github.com/alidi24/bearing-rul-prediction.git
