Case Study:
Transmission Casing

UK Automotive Consultancy

To predict and reduce the noise generated by a transmission system due to gear whine phenomenon.


  • Dynamic analysis of the noise generating gear pair
  • Determination of the transmission error and its propagation while rotating
  • Optimization of the gear micro geometry to increase contact ratio and make transmission smoother

Optimizing the gear pairs helped in reducing the transmission error, reducing a major component of gear whine.
