Abstract

Energy-efficient wind turbines with longer lifespans are needed. Current energy industry advances need this necessity. So, knowing how load conditions affect wind turbine functioning is crucial. This field studies steady-state stresses and deformations. "The vibration characteristics of the NREL offshore 5-MW blade (HAWT)" were tested and studied (126 m). SOLIDWORKS created the 3D wind turbine blade model, which was exported to ANSYS/Workbench19 for finite element numerical simulation. The wind turbine blade was tested in a steady condition at its maximum rated power (12.1 rpm). This study generated wind blade parts from three different materials: carbon fiber reinforced plastic, E-glass fiber, and Kevlar. The outcomes revealed "the von-Mises stresses, total deformations, first ten natural frequencies, and mode morphologies of the NREL 5-MW wind turbine blade. Steady-state" research showed that carbon fiber reinforced plastic (CFRP) produced the fewest stresses, making it the best material. CFRP was best. Hence, CFRP should be used. Vibration research showed that CFRP material has the maximum structural stiffness. It also lacks high frequencies and mode formations. This interpretation was right.
