Comparison of finite-element predictions and experimental data for the forced response of the DOE 100-kW vertical-axis wind turbine
A specialized finite-element capability has been developed to predict dynamic structural response of the vertical-axis wind turbine (VAWT). This report is concerned with evaluating this finite-element analysis technique. To achieve this, several types of experimental data taken from the DOE 100-kW rotor are compared with predictions. These data include parked rotor natural frequencies, very low wind centrifugal and gravitational load response, and vibratory response from wind loads covering the rotor operational spectrum. Generally, the agreement between theory and experiment is very satisfactory. It is concluded that the analysis package is suitable for engineering design. Short-comings observed in modeling accuracy are believed to be due primarily to inadequacies in blade aerodynamic-load calculations.
