Author: David Malcolm and Olamide Ajala-InyangPublication: Journal of PhysicsYear Published: 2024 Abstract. This paper describes a project for predicting and measuring the structural response of a 70 kW vertical axis wind turbine (VAWT), while offering insights for optimizing efficiency and ensuring longevity. We employ the traditional frequency response approach and model the turbine behavior using…
Author: Erik Mollerstrom, Fredric Ottermo, Jonny Hylander, Hans BernhoffYear Published: 2014 Eigen frequencies of a vertical axis wind turbine tower made out of laminated wood which are both bolted to the ground and supported by guy wires are studied and compared. Using beam theory, an analytical model taking the guy wires into account for calculating…
Author: Erik Mollerstrom, Fredric Ottermo, Jonny Hylander, Hans BernhoffPublication: EWEAYear Published: 2014 Resonance analysis for a vertical axis wind turbine is performed. The turbine may be described as semi-guy wired, being bolted stiffly to the ground as well as supported by guy wires. The influence of the first mode eigen frequency of the guy wires…
Author: David MalcolmPublication: Engineering StructuresYear Published: 1988 A method is presented for the frequency response analysis of a Darrieus rotor wind turbine subject to turbulent flow. A number of time series vectors of longitudinal and lateral turbulent velocities are generated and the interaction with a two-bladed rotor is carried out with a double multiple streamtube…
