| 摘要 |
<p>The invention relates to a wind turbine blade (5) comprising one or more oscillation dampers (11) for damping oscillations or vibrations of the wind turbine blade (5). The dampers (11) comprise one or more first damper parts (13) having one or more first damper part surfaces (17). The first damper parts (13) being rigidly connected to the blade (5) and/or being a part of the blade (5). The dampers (11) further comprise one or more second damper parts (12) having one or more second damper part surfaces (18), wherein the first damper part surfaces (17) and the second damper part surfaces (18) are arranged to move relatively to each other during the oscillations. Even further the dampers (11) comprise a load transferring coupling (32), directly or indirectly coupling the first damper part surfaces (17) and the second damper part surfaces (18), so that the relative movement result in a oscillation-damping dissipation of kinetic energy. The invention further relates to a wind turbine (1), an oscillation damper (11), a method for damping oscillations of a wing turbine blade (5) and use hereof.</p> |
