Initial structural response measurements for the Sandia 34-meter VAWT (vertical axis wind turbine) Test Bed
Sandia National Laboratories (SNL) has designed and constructed a 34-meter diameter vertical axis wind turbine (VAWT) Test Bed. The machine will be used to advance research in aerodynamics and structural dynamics, improve fatigue life prediction capabilities, and investigate control algorithms and systems concepts. The Test Bed has extensive instrumentation including 70 strain gauges to measure blade and tower response. Immediately after the blades were mounted, blade gravity stresses were measured and a modal analysis on the stationary rotor was performed to determine zero rpm modal frequencies. Assembly and start-up tests have been completed, and testing is in the machine characterization phase. Resonance surveys are underway to fully characterize the modal frequencies and mode shapes of the rotor, drive train and support cables. Measured gravity stresses, centrifugal stresses, and modal frequencies are compared to predicted values. 11 refs., 12 figs., 1 tab.
