摘要:
A wind turbine blade comprising one or more oscillation dampers for damping oscillations or vibrations of the wind turbine blade. The first damper parts being rigidly connected to the blade or being a part of the blade. The dampers further comprise second damper parts, wherein the first damper part surfaces and the second damper part surfaces are arranged to move relatively to each other during the oscillations. Even further the dampers comprise a load transferring coupling, coupling the first damper part surfaces and the second damper part surfaces, so that the relative movement results in a oscillation-damping dissipation of kinetic energy.
