Non-destructive testing of wind turbine blades
This paper applies bibliometric analysis to classify existing blade damage detection methods, comparing major non-destructive testing techniques, including strain data monitoring, vibration data monitoring, acoustic measurement, ultrasonic testing, thermal imaging, and image. . This paper applies bibliometric analysis to classify existing blade damage detection methods, comparing major non-destructive testing techniques, including strain data monitoring, vibration data monitoring, acoustic measurement, ultrasonic testing, thermal imaging, and image. . Wind turbine blades, as core components of wind power systems, require effective health monitoring and damage identification to ensure stable turbine operation and enhance economic efficiency. Serving as a preliminary experiment. . However, in order to fully exploit energy of wind power the construction elements of the wind turbine should be inspected periodically. Wind turbine blades are complicated objects for inspection because they have an arbitrary curved surface, are multi-layered, have variable thickness and are made. . Defects or damage to wind turbine blades (WTBs) not only reduce the lifetime and efficiency of wind turbine electricity generation but also increase monitoring errors, safety hazards, and maintenance costs. -
