Análise de falhas em peça de estrutura de fixação de aerogerador de pequeno porte

Abstract

With the price reduction of deployment costs and innovations in generating renewable energy structures, nowadays the demand for renewable energy installation has increased exponentially. But like all structures these structures are conditioned to failures of various types. This work presents a failure analysis of a part, a support structure of a small wind turbine aimed at micro power generation. In order to conduct the faulure analysis, microscopic analyzes, fractographs, macrographic analyzes and finite element modeling were performed. Thus, the causes of failures were identified, such as poor choice of materials and some errors in the design of the part.
