Abstract

This study aims to analyze the natural frequency of horizontal axis wind turbine blades using the finite element method (FEM) through ANSYS 2023 and Solid works 2021 software as 3D images. The main focus of this study is on two types of blades, namely taper and taperless, using Glass Fiber Reinforced Polymer (GFRP) material with a NACA 4412 airfoil profile. Until now, there is no standard for the geometry of small-scale wind turbine blades, so blades are generally designed flexibly according to needs. The parameters analyzed include the influence of geometric shape, material properties, and mass distribution on the value of the natural frequency of the structure, as well as the potential for resonance. The results show that the geometric shape of the blade has a significant effect on the value of the natural frequency, where the taper blade produces a higher frequency than the taperless blade.
