505			_aIn order to quantify backlash loads in the power train of wind turbines, a non-linear, three dimensional, transient dynamic model is developed. The numerical model includes all relevant mechanisms and structural components of the power train and in particular a detailed model of the planetary gearbox which accounts for all clearances of bearings and gaps in between contacting gear teeth. Experiences in the numerical modeling and analysis of dynamic backlash phenomena are commented and stipulations are done with respect to possible mechanisms which produce power train failure. Finally, the application example illustrates the power train dynamics in the case of an asynchronous generator which operates with nominal speeds of 1000 RPM and 1500 RPM respectively.
