Modelling of Technical Systems: Application to Hydrodynamic Torque Converters and Couplings

First a short survey of modelling of technical systems is presented. The different methods of modelling are applied to hydrodynamic torque converters and couplings. The results of linear modelling around an operating point, of nonlinear modelling for larger operating areas and of hybrid modelling using simplified physical laws are illustrated. Simulations for large excitations show the validity of the models. The advantages and disadvantages of the different methods are discussed.
