Influence of hydrodynamic planetary journal bearings on the NVH-behavior of wind turbinesEinfluss hydrodynamischer Planetengleitlager auf das NVH-Verhalten von Windenergieanlagen

The growth of the wind energy sector is confronted with stringent noise regulations, particularly concerning tonal noises from wind turbines (WTs). These tonal noises, originating from drivetrain vibrations such those caused by gear meshing, are transmitted as structure-borne sound through the WT and ultimately emerge into the surrounding environment as sound emissions. Given that tonal noises are irritating to humans, there is a need for early-stage noise, vibration, and harshness (NVH) mitigation.
