| Research Abstract |
First, responses of a rotating rigid blade and a rotating flexible blade to the rotational speed were investigated. The synergetic effect of the excitation due to the blade weight and that due to wind which varies by height was clarified. Next, an unstable vibration of a tower with a two-blade turbine was investigated. Finally, the suppression effect of a fluid damper to the tower vibration was investigated.
