the bearing and gear fault datasets are collected from Case Western Reserve University bearing data center, gear vibration dataset of University of Connecticut.
| Health states of bearing | Health states of gear |
|---|---|
| Normal | Chipping 1 (High) |
| Inner race 0.007 | Chipping 3 (Middle) |
| Inner race 0.0021 | Chipping 5 (Low) |
| Outer race 0.007 | Crack |
| Outer race 0.014 | Missing |
| Outer race 0.021 | Spalling |
| Rolling element 0.014 | Healthy |
In this paper, a signal-to-image conversion method [50] is used to transform the original 1D vibration signals into 2D gray images. code: signal-to-image conversion [50] L. Wen, X. Li, L. Gao, Y.

Before begin, please separate the training data of different health states into folders in foldergray_images\\.
The code for training MACGAN and generate gray images istraining and generating.py, you may also customize the parameters in config part in training and generating.py. The generated images will be saved in foldergenerated images\\.
Our SpectralNormalization code is based on (https://github.com/IShengFang/SpectralNormalizationKeras)
