Abstract: The continuous demand for increase in power output for new wind parks under strict cost
constraints, the greater wind resource at elevation and the desire for fewer machines per Mega-Watt to
reduce operations resulted in a demand for bigger turbines. The drive train is an important component
in realizing reliable and robust wind turbines. This paper investigates a geared wind turbine. In this
type a gearbox is used to convert the low rotor speed to the required high generator speed. In the
market several solutions are available to constrain the gearbox in the nacelle. The used configuration
significantly determines the gearbox response to rotor loads and the transmission of gearbox
vibrations to
the turbine. This paper investigates the effectivity of three configurations: the three point mounting,
the double bearing configuration and the hydraulic damper system. The fexible multibody modeling
technique can be used to accurately characterize gearbox dynamics. The goal of this work is to use an
experimentally validated multibody model of a wind turbine drive train to characterize the ability of
the three configurations to minimize the introduction of
non-torque loads in the gearbox and the ability to isolate the gearbox vibrations from the rest of the
