Abstract
This paper investigates gear tooth fatigue damage in a 500 kW wind turbine using FLEX5 and own
multibody code. FLEX5 provides the physical wind eld, rotor and generator torque and the multibody
code is used for obtaining gear tooth reaction forces in the planetary gearbox. Dierent turbulence
levels are considered and the accumulated fatigue damage levels are compared. An example where the
turbulence/fatigue sensitivity could be important, is in the middle of a big wind farm. Interior wind
turbines in large wind farms will always operate in the wake of other wind turbines, causing increased
turbulence and therefore increased fatigue damage levels. This article contributes to a better understanding
of gear fatigue damage when turbulence is increased (e.g. in the center of large wind farms or at places
where turbulence is pronounced).
