Simulación y pruebas de laboratorio de un aspa de turbina de viento de 600W de acuerdo a la Norma IEC-61400-2

Abstract

In the present work is shown the numerical simulation performed by means of finite element software (FEA) and the static mechanical tests using extensometric techniques for a wind turbine blade of 600W in accordance with the international standard IEC 61400-2. A NACA 4412 profile was used and the loads applied were selected according to the following load hypotheses described in the standard: normal operation, maximum thrust, immobilization with wind load and maximum exposure. A methodology was developed for both the simulation and for the laboratory tests, the data of the microdeformation measured by extensometry were also analyzed and compared with those obtained by the numerical simulation. Concluding that the analysis of finite elements is a key step prior to manufacturing that allows us to save resources and gives us parameters to perform both manufacturing and testing. Laboratory tests are necessary to ensure safe and reliable functioning of the blade during its useful life.
