· Special wind- and wave excitations and low damping of wind turbine structures can lead to both, extreme resonance situations and increased fatigue loads on the tower.
· Key parameters for vibration design are first and second tower eigenfrequencies and their corresponding damping.
· The trend to lower eigenfrequencies and larger deformations with low damping requires special damping devices that controls the damping of the structures.
· The input from ESM focus on the damping control of wind turbine structures.
Dr. Lukas Schneider, Vibration Engineer, ESM
-Small damping values of low and high frequency eigenmodes in rotor
blades lead to resonances that have impacts on the structural integrity
and radiation of noise.
-It is shown in a systematic way how damping can be introduced into the
eigenmodes of blades and resonant behaviour can be prevented.
-The focus is on edge-wise vibrations, tonalities and broad-band radiation of the noise.
