Vdamp® for Wind Turbines:
With vast improvements in the aeroacoustics blade design over the past years, the mechanical noise had become audible. Together with the growing sizes of onshore turbines, more stringent regulations, and low wind speed operations, drivetrain noise and tonality has become more challenging. Geislinger Vdamp®, a broad-band torsional damper, gear-integrated or attached to the rotor of a direct-drive turbine, dampens torsional excitations caused by gear teeth mesh, respectively pole transition. These torsional vibrations causing the structure-borne noise, which is transferred to the entire wind turbine structure, is dampened effectively at its origin. Wind turbine tonalities can be avoided, respectively the overall sound pressure is reduced.
