Gearbox dynamic modelling

The paper reports on current developments in gearbox dynamic modelling. It refers to Müller's one-mass two-parameter (stiffness and damping) gearbox model with rectilinear vibration. The paper shows that there is a need to develop a new model, which would incorporate torsional vibration. The paper refers to the previous papers on gearbox dynamic modelling published by the author in journals and conference proceedings. In the present paper, the influence of the clutch damping coefficient and one random parameter value from the three-parameter error mode, and that of the interaction between error parameters on the vibration generated by a gearbox system, is analyzed.
