A Basic Approach to Gearbox Noise Prediction 821065

This paper provides an overview of a strategy for the prediction of noise from industrial gearboxes. A review of the history of predictive noise control in gearboxes is given. The historical lead is followed in developing the strategy, but significant changes in the approach to predictive noise control have been made. The heart of the approach is the dynamic modeling of the gearbox from inside out. Thus one must start this process with the prediction of the internal dynamic response of the gear train system.
This paper then details the computational strategy for the determination of the dynamic response of the internal gearbox components. The approaches presented here are significant departures from those carried out in the past.
