Wind turbines are prone to vibration problems. According to research data, about 40% of all wind turbines have high vibrations which exceed vibration limits. These vibrations cause structural loads, increased wear, adverse start-up conditions, and often vibration-related shutdowns.

read moreTorsional vibration is the angular oscillation of a rotating object such as a drive shaft, caused by fluctuating torsional levels. It is a common occurrence in power transmission systems such as engines and automotive drivetrains. Torque transmission is rarely “smooth” since the torque in the system…
