Investigating How an Artificial Neural Network Model Can Be Used to Detect Added Mass on a Non-Rotating Beam Using Its Natural Frequencies: A Possible Application for Wind Turbine Blade Ice Detection.

Non-contact vibration monitoring of rotating wind turbines using a semi-autonomous UAV. With the recent demands for more efficient clean renewable energy sources, wind turbines are designed that have large rotor blade diameters. These large-sized wind turbines need to be periodically monitored to prevent catastrophic failures.

A multi-rotor wind turbine (MRWT) is a concept that can reduce the size of the rotor blades compared to a single-rotor wind turbine (SRWT). Making a cost-optimized MRWT requires a detailed understanding of its stability properties. This paper aims to establish a physical and intuitive representation of whirling modes for three

Finally, the mode shapes of non-rotating and rotating turbine blades were obtained using VIC-3D which are shown in Figs. 7 and 8, respectively (it was processed for three blades only). The analysis explained in this section shows that DIC technique can be applied to obtain the vibration characteristics of a wind turbine during natural conditions.

5 · Wind turbine technology converts the mechanical energy of the wind into electrical energy, through the rotation of rotor blades, which is the driving force for the generator 9,11.

Wind turbines, similar to many rotating structures, rely on the structural integrity of the blades used to generate the torque necessary for rotation and ultimately the generation of electric energy. These blades are exposed to extreme operating conditions including, but not limited to, continuous varying loading, ultraviolet radiation, temperature

Accelerometers and piezoelectric sensors have accompanied the measurement setup in the rotating and non-rotating wind turbine components to assist in giving an improved understanding of the system dynamic behaviour. A servo-motor provides the input transient torque of the main shaft to get the desired velocity as well as velocity control

We then used this blade in a series of experiments that mimicked the response of a non-rotating wind turbine blade to the incoming wind by placing the blade at the center of the test section of a wind tunnel.

The angle of attack (AoA) is the key parameter when extracting the aerodynamic polar from the rotating blade sections of a wind turbine. However, the determination of AoA is not straightforward using computational fluid dynamics (CFD) or measurement. Since the incoming streamlines are bent because of the complex

The blade is one of the core components of a wind turbine. Consequently, monitoring the dynamic response of the blades is essential for improving the reliability and safety of their operation. 1,2 During their design life of 10–30 years, wind turbine blades can accumulate an enormous volume of load cycles, making fatigue life an important design

ABSTRACT. Wind turbine blades'' dynamic behavior must be well investigated during the design process in order to avoid resonance.
