ANÁLISE DINÂMICA DE UMA VIGA EXCITADA PELO CARREGAMENTO RANDÔMICO DO VENTO

Abstract

. This project aims to simulate random wind loading in immersed structures, which can be used for a performance and integrity analysis of the structural systems of a wind turbine. For this, a beam with linear behavior modeled from the theory of Euler-Bernoulli beams was used. Thus, the spectral density was generated, using the Kaimal Method, for the development of wind speed. And, later, the drag force that it exerts when in contact with the beam was calculated, making it possible to observe its dynamic behavior. Finally, the values found using the ANSYS APDL software were compared with the methodology developed in this work. And the auto-spectra of the structural response were generated in order to show the frequency range excited by the proposed force.
