A mathematical model was built up and a computer programme was developped in order to simulate the drive line of a vehicle. Particular attention was given to the possibility to incorporate non linearities such as teeth clearence and torsional stiffness of the clutch plate. With the model it is possible to study rattling and hammering of the gearbox and in particular the influence of the clutch on it. Also the influence of a vibration absorber on resonance frequencies is investigated. Due to a extrapolation of the programme, we are also able to analyse the interaction between the torsional stiffness of the driveline and the axle vibration on his suspension.
