Abstract

In order e.g. to provide an vibration damper which does not need to be fluid tightly surrounded, there is disclosed a wind turbine blade comprising at least one wind turbine blade vibration damper, the at least one damper comprising one or more first damper surfaces, and one or more second damper surfaces, and where the one or more first and the one or more second damper surfaces are provided in an interior of the blade and are arranged to move relatively to each other during vibrations of the blade, and a load transferring coupling, coupling the first and second damper surfaces, so that a relative movement of the damper surfaces result in an vibration-damping dissipation of kinetic energy in the load transferring coupling, and wherein the load transferring coupling comprises a viscoelastic foam.
