Voltage induced damage progression on the raceway surfaces of thrust ball bearings, Part II: High Speed Measurements

This set of data is obtained by André Harder during his experiments on the progression of voltage induced bearing damages. The experiments were made on the bearing test rig at the Institute of Product Development and Machine Elements of the Technical University of Darmstadt in the time between December 2021 and March 2022. Thrust ball bearings were tested to investigate the damage progression on the bearing surface without destroying the bearing. The description of the test parameters, the test procedure and the explanation of the naming convention of the data can be found in the first part of the published data (see related sources). This set of data gives three additional domains of the measured data. The high speed radial and axial acceleration measurements obtained every minute of the test run are part of the A-domain. The high speed measurements of the electric voltage applied on the bearing and the corresponding electric current are part of the E-domain. Lastly, a measurement of the electric impedance of the bearing was obtained, before applying the damaging electrical signal. These measurements are part of the I-domain.
