Análisis modal de un mecanismo elevador para transporte vertical de álabes en turbinas eólicas con eje horizontal en tierra y en mar

Abstract

This work deals with modal analyses of a ‘wind turbine – climbing mechanism’ system, which can be used for installation or replacement of blades of wind turbines. The CAD models of a wind turbine and a climbing mechanism are developed in the software Solidworks, which are imported into ANSYS Modal state-of-the-art code, where a structured mesh is created for simulations. In order to evaluate resonance possibilities on the system, three installation configurations are considered for simulations, from which mode shapes and natural frequencies of wind turbine components are obtained. Some results from simulations are compared with those available in literature for verification purposes. This study provides basis for technical feasibility of the installation concept analyzed in this work.
