Author: K. McLaren, S. Tullis and S. ZiadaPublication: McMaster UniversityYear Published: 2007 The motivation for this project arose from an expected vibration source of a small-scale vertical axis wind turbine currently undergoing field-testing. The turbine consists of three 3-metre long vertically aligned blades each fixed to the central shaft by two horizontal arms and separated…

Author: Thomas Carne, D.R. Martinez, S.R. IbrahimPublication: Sandia National LaboratoriesYear Published: 1983 A new testing technique and the Ibrahim time domain (ITD) modal identification algorithm have been combined, resulting in a capability to estimate modal parameters for rotating blade systems. This capability has been evaluated on the Sandia two-meter, vertical-axis wind turbine. Variation in modal…
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…
