Abstract: Reliable gearbox design calculations require accurate load data and sufficient insight in dynamics of the entire drive train. This paper describes the scope of a research project undertaken by Hansen Transmissions International, in cooperation with Katholieke Universiteit Leuven aiming at development and validation of advanced multibody modelling and simulation techniques. Implementation and validation through extensive measurements of a purely torsional multibody model for use in early gearbox design stages is explained. Based on the shortcomings of such a model, it is explained which additional degrees of freedom can bring added value. Moreover the effect of flexibility, with focus on coupling structures, on the drive train modal behaviour is discussed.
