Wind turbines are structures which have the tendency to vibrate easily due to the nacelle mass placed on top of the slender, elastic mast. They are heavily excited by the varying loads caused by wind, waves, earthquake, rotation of the rotor, switching and control procedures. The vibration behaviour has a big influence on the deformations, the inner stresses and the resulting ultimate limit state, fatigue and operating life of the wind turbine.
