Abstract
This paper presents a study of the structural response of a rotor blade that was designed for a 1 MW floating tidal turbine device. The 8 m long blade was manufactured by ÉireComposites Teo and its structural performance was experimentally evaluated under mechanical loading in the Large Structures Research Laboratory at National University of Ireland Galway (NUIG). The FE model of the rotor blade was developed based on layered shell elements. A digital twin of the rotor blade was developed and validated in this paper. In effect, the digital twin is a finite element model (FEM) generated in ANSYS. By simulating the blade response under the design loads using the digital twin, a difference of 3% is found in the blade tip deflection between the physically measured test results in the laboratory and numerical prediction from the digital twin. The results not only guarantee that the blade can withstand the maximum design loads, but also demonstrate good accuracy of the digital twin.
