10:00 - 10:30 Novel condition monitoring approach for journal bearings in wind turbines based on surface acoustic waves – current state of research and challenges

Thomas Decker - Group lead design, RWTH Aachen
  • Correlation between surface acoustic wave measurements and the tribological behavior of a journal bearing
  • Application of the technology to a wind turbines gearbox system
  • Discussion of test result from the system level
  • Remaining challenges on the way towards field application

10:30 - 11:00 Hybrid signal processing-AI for remaining useful life estimation of wind turbine bearings

Jan Helsen - Professor, VUB


  • To plan optimized maintenance, condition monitoring methods should go beyond early fault detection to estimation of remaining useful operational time
  • AI offers potential for early detection but should be made explainable to give confidence to maintenance engineers
  • Signal processing allows to bring physics in the detection models
  • Field pilot results are shown to illustrate the methods

11:45 - 12:15 Accurate Prediction of Rolling Bearing Life Applying Ultrasonic Testing

Dr. Brice Tchemtchoua - Global Business Development Manager - Wind, NSK Deutschland GmbH

A method to predict rolling bearing life caused by non-metallic inclusions with high accuracy has been suggested by combining two technologies:


• The evaluation of bearing steel using ultrasonic testing

• A method for evaluating bearing life and fatigue limit.
