摘要

This issue of Insight contains a special focus on condition monitoring (CM) and includes topical articles on the subjects of wind turbine CM, vibration analysis and signal processing, and gearbox CM. The wind energy industry continuously demands significant improvements in wind turbine maintenance strategies through the use of condition monitoring systems. Regardless of their design, wind turbines have rotating parts that need to be monitored during operation in order to avoid unpredicted failures. The paper by Rafael el al describes experiments carried out at Newcastle University on the monitoring of gearbox contact fatigue using acoustic emission and vibration analysis.
