Análises e verificações de torres tubulares de aço para aerogeradores

Abstract

With the growing demand for electric energy and the society's awareness about the preservation of the environment, it became necessary to use energy sources that cause less impact on nature and that are inexhaustible. One of these sources is the wind, exploited for energy formation through the implementation of wind turbines, which are coupled in towers, which are mostly made up of overlapping steel rings. The towers are subject to a serie of actions that can lead to their failure due to fatigue, or due to instability of the metallic shell because of the minimization of its thickness. In this sense, the present work aims to analyze the structural conduct of towers based on academic studies focused on structural analysis, structural design and dynamic analysis of tubular steel towers for horizontal axis wind turbines.
