Noise and vibration measurements of 50 kW Vertical Axis Wind Turbine gear box
Abstract
An analysis of noise and vibration measurements was carried out for the gear box and the power house panels of the 50 kW Vertical Axis Wind Turbine (V.A.W.T.) operating at Christopher Point on Vancouver Island, B.C. The spectra of noise and vibration signals show strong peaks at the gear mesh frequency and its harmonics even under light load conditions. The sound power radiated from the power house panels is significantly higher than that radiated by the gear box casing. The analysis also indicates misalignment of the pinion shaft or eccentricity of the pinion and errors in the gear tooth profiles.
