摘要：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.
