Dimensionality Reduction of Active Vibration Data for Detection and Monitoring of Progressive Damage in Wind Turbine Blade

Abstract

The present work considers the use of an active vibration monitoring system for wind turbine blade SHM. A test campaign is conducted with a 52-meter commercial wind turbine blade, investigating the potential for detection and monitoring of damage using the active vibration monitoring system. A crack is manually induced in the shear web laminate of the wind turbine blade, and progressive damage propagation is obtained during fatigue testing.
