Abstract:To analyze the influence of the blades force and the blade centrifugal
stiffening effect on wind.induced response of wind turbine tower.the
wind.induced response of wind turbine tower was investigated,with the
centrifugal stiffening effect taken into account.The fluctuating wind
velocity time series of wind turbine were simulated by the harmony
superposition method,and the theoretical vibration equation of blade
involving centrifugal stifiening effect was derived.The wind-induced
responses of blade and tower were calculated in three conditions,and the
tower top displacement and the relative errors in each condition were
recorded.The results show that the blades force on tower has great
effect on the dynamic response of tower.and the wind-induced response of
tower Was reduced by centrifugal stiffening effect.Hence,the influence
of the centrifugal stiffening effect should be considered in the dynamic
calculation.
