VAWTDYN - A numerical package for the dynamic analysis of vertical axis wind turbines
Abstract
The dynamic behavior of wind turbines is a major factor governing their overall fatigue life and reliability. This paper describes a package developed for the dynamic analysis of the Darrieus vertical axis wind turbine. The model on which the package is based includes the major rotor elastic degrees of freedom, gyroscopic effects, and structural damping. The equations of motion are discussed and several example solutions are presented. Comparisons are made between model predictions and data from operational rotors.
