Noise generated in automotive transmissions can cause annoyance to passengers and can affect customer satisfaction. This noise may be a result of complex interactions between the transmission, the vehicle body and driving conditions and is thus very difficult to analyze. A good starting point however is to assume that the transmission noise is due to transmission error in the gears. Besides being amenable to mathematical analysis, research has shown that transmission error is indeed a major factor of noise for a pair of meshing gears. This assumption has however not been tested or extended to epicyclic gear systems that are widely used in vehicular automatic transmissions. We present here a design consultant that allows the designer to configure various transmissions, specify various input parameters and study the effect of parameter variations and errors on the overall transmission error. We build upon our previous work by presenting detailed implementation issues in the development of such systems.
