Accelerometric measurements from the rolling bearing test rig of the Dynamic and Identification Research Group (DIRG), Department of Mechanical and Aerospace Engineering, Politecnico di Torino. Goals: • Vibration Monitoring, Bearing Diagnostics, Damage detection, Damage localization, Damage classification, Damage assessment. Features: • high-speed spindle driving a hollow shaft supported by a couple of identical roller bearings B1 and B3. B1 is the bearing under analysis and features various damages. • two damage types (indentations on a roller and on the inner ring) and severities (0, 150, 250, 450 µm). • a central, larger roller bearing (B2) is loaded through a sledge generating a controlled radial force measured by a load cell. • lubrication is obtained by oil injection into the hollow shaft. • a K-type thermocouple is used to monitor the temperature (manually recorded). • two triaxial accelerometers are mounted on the supports of bearings B1 and B2. Dataset: • stationary acquisitions at different speed & load combinations (speed: 0, 100, 200, 300, 400, 500 Hz; load: 0, 1000, 1400, 1800 N). • endurance acquisitions of the bearing featuring the 450µm roller indentation. Monitoring of the damage evolution for about 230 hours under the same speed and load condition. The extended description of the dataset can be found in the attached pdf "Description and analysis of open access data" or in: A.P. Daga, A. Fasana, S. Marchesiello, L. Garibaldi, The Politecnico di Torino rolling bearing test rig: Description and analysis of open access data, Mechanical Systems and Signal Processing 120 (2019) 252–273. doi:10.1016/j.ymssp.2018.10.010.
