Geislinger Vdamp®, a broad-band torsional damper, is integrated directly to the gearbox and solves the problem at the source of the structure-borne noise, the excitation from the gear teeth. Wind turbine tonalities can be avoided, respectively the overall sound pressure is reduced. Learn more 👉 bit.ly/35ysfxP
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 powertrain solutions bear the potential to avoid turbine tonalities, respectively to reduce their overall sound pressure. In medium- and high-speed wind turbines, the Geislinger Damper, the Geislinger Vdamp® or the Geislinger Coupling are integrated directly to the gearbox and solve the problem at the source of the structure-borne noise, the excitation from the gear teeth. For direct drive wind turbines, the Geislinger Vdamp®, attached to the rotor of a direct-drive generator, dampens torsional excitations caused by pole transition. The resulting torsional mode, which is responsible for the formation of mechanical structure-borne noise and its propagations to the entire structure of the wind turbine, is thus effectively damped at its origin.
