- In present-day, the engineering challenge around a drive train design for a wind turbine is not only to enhancesystem reliability but also to reduce the turbine top mass. These requirements together with the trend of upscaling affect many system characteristics and parameters. The proposed contribution presents a model tostudy torsional drive train vibration dynamics of a generic indirect drive multi-MW wind turbine. The mainfocus lies on developing a fully parameterized computational model of a multi-stage gearbox which fulfillsthe requirement of a proper gear dynamic representation appropriate for multibody formalism as well asthe requirement to be computationally efficient. Two different strategies for modeling the gear contact arestudied and compared in time domain. An analysis of a multi-stage gearbox together with a generator load and a turbine specific nondeterministic excitation was carried out. It is believed that the obtained results will help designer to improve drive train components and to enhance wind turbine reliability and cost efficiency.
