    Determination of cracks in wind turbine blades by simulating sensors through finite element studies
    (Atena Editora, 2025-01) Monzón, Tomás Facundo; Anton Cabral, Lautaro Agustín; Bejarano, Pablo Silvestre
    The importance of wind energy is increasing due to its relative share in the global market. Especially in Argentina, projections are important, which not only concerns operation, but also maintenance tasks. These tasks can have a great impact on productivity if stop times are significantly prolonged. Based on several investigations carried out during two years, we continued with the study of a three-dimensional model of a wind turbine blade, using the finite element analysis technique, to determine the presence of cracks in the part by means of the analysis of deformations due to the wind forces to which it is subjected. The detections of the changes in the mechanical behavior of the blades will allow us to consider that they can be monitored in real time and determine if they present anomalies due to failures in their structure. In addition, it is intended as one of the purposes to deter mine the characteristics such as the shape of the crack which according to this can help the optimization and implementation of a maintenance plan.

    Identificación de zonas de gran deformación en alabes de aerogeneradores por elementos finitos en condiciones de viento de Chubut
    (Actas de Jornadas y Eventos Académicos de UTN, 2024-06) Monzón, Tomás Facundo; Bejarano, Pablo Silvestre
    A partir de un modelo entres dimensiones de un alabe y con la técnica de análisis por elementos finitos, se simularon condiciones de vientos de la provincia de Chubut y detectaron áreas que soportan mayores tensiones mecánicas. Dichas zonas son claves para considerar el posicionamiento de sensores que permitan tener un control en tiempo real del comportamiento mecánico de los alabes. Los resultados obtenidos abren el camino a futuros desarrollos que mejoren el entendimiento de estas estructuras compuestas de diferentes materiales.
