Investigation of the effect of bending twisting coupling on the load in wind turbines with superelement blade definition Gözcü, Mehmet Ozan; Kayran, Altan (2014-01-01)
Investigation of the effect of bending twisting coupling on the loads in wind turbines with superelement blade definition Gözcü, Mehmet Ozan; Kayran, Altan; Department of Aerospace Engineering (2014) In this thesis study, the effect of off-axis plies in the spar caps of a wind turbine blade on the damage equivalent loads in a wind turbine system is investigated. The off-axis plies in the spar caps are exploited for load alleviation in the whole turbine system since the off-axis plies induced bending-twisting coupling into blades of wind turbine. Damage equivalent load is used to assess the effect of bend twist coupled blade on the fatigue load reduction in the whole wind turbine system. NREL's 5 MW turb...
Investigation of the effect of bending twisting coupling on the loads in wind turbines with superelement blade definition Gozcu, M. O.; Kayran, Altan (2014-01-01) Bending-twisting coupling in the composite blades is exploited for load alleviation in the whole turbine system. For the purpose of the study, inverse design of a reference blade is performed such that sectional beam properties of the 3D blade design approximately match the sectional beam properties of NREL's 5MW turbine blade. In order to appropriately account for the bending-twisting coupling effect, dynamic superelement of the blade is created and introduced into the multi-body dynamic model of the wind ...
