| Abstract: | Transverse vibration for wind turbine tower was analyzed combined with finite element method and theoretical computation.It estimated the resonance region of tower by contrasting natural frequency and wind vibration frequency.It showed and analyzed the simple computation function for the maximal amplitude,the inertial force and characteristic moments when tower vibrated in the transverse direction.It also showed examples.Fatigue damage for tower which vibrated in transverse direction was calculated.The resu... |
