A mathematical model representing the torsional characteristics of a machine train including a gear has been developed incorporating a number of features which are usually neglected, namely, damping and flexibility in the bearings and damping, backlash and pitch error in the gear teeth. This model has been used in conjunction with a computer simulation language to predict the performance of a geared compressor in which there is a torsional resonant frequency close to twice the motor speed.
