Outline of Final Research Achievements

Wind turbines are classified into (A) land and offshore wind turbines whose bases are fixed in ground and (B) offshore floating wind turbines. In the former case, we obtained the resonance curve of a rotating blades, and showed that vibration of a rotating blade can be suppressed by a centrifugal pendulum vibration absorber and and a tuned mass damper. Unstable vibrations of a two-blade wind turbine is investigated.
In the latter case, stable vibration due to wind force and unstable vibrations due to heaving motion made by sea wave were investigated. In addition, it was clarified that the motion cab be suppressed by pendulums.
