Here you can download the dataset files of the experiment to detect defects in fluid friction bearing units. There are two types of files. Files named "data..." are for training networks. The first digit in the file name indicates the experiment number, and the second one indicates the defect class. In total, there were 4 types of the state of the experimental stand. Correspondence of the defect number and its type: 1 - no defects, 2 - misalignment in the coupling, 3 - imbalance, 4 - bushing with defects.
The second type of files called "Series..." are intended for testing the algorithms used. The final fault labeling file should be prepared based on the data of these experiments. The true type of defect is hidden, do not use the data from these files when training.

Information on the uploaded participant file is located in the Overview => Evaluetion.
Due to the small amount of data, a test sample is available to participants. Therefore, we hope for your honesty.

The experiment time was 10 min. The frequency of obtaining data on the vibrations of the rotor is 1000 sig/sec. The frequency of temperature data acquisition is 1 sig/sec.
Data Description:
Each column corresponds to a certain parameter, the rows contain the readings from the sensors in each time period. Temperature sensor data is duplicated for every second to simplify data correlation.
1 column of the array - horizontal oscillations in the left bearing, in Volts,
2 column of the array - vertical oscillations in the left bearing, in Volts,
3 column of the array - horizontal oscillations in the right bearing, in Volts,
4 column of the array - vertical oscillations in the right bearing bearing, in Volts,
5 column of the array - horizontal oscillations in the left bearing, taking into account smoothing, in Volts,
6 column of the array - vertical oscillations in the left bearing, taking into account smoothing, in Volts,
7 column of the array - horizontal vibrations in the right bearing, taking into account smoothing, in Volts,
8 column of the array - vertical oscillations in the right bearing bearing, taking into account smoothing, in Volts,
9 column of the array - temperature in the left bearing, in Ohms,
10 column of the array - temperature in the right bearing, in Ohms.
