Certain categories of vehicle users have very high expectations of comfort, with noise playing a major role in these requirements. Market research demonstrates that gear whine is an important failure mode for transmission NVH. French major OEM is developing new design methodologies which will guarantee improved NVH quality performance in all new gearbox designs. A transmission NVH simulation and analysis tool has been tested on pre-existing transmission designs to assess its capabilities in the prediction and resolution of gear whine problems. The software tool successfully predicted the vibration response of the current gearboxes. The validated model has been used to simulate parametric sensitivity of NVH performance and the software simulation tool is now part of the OEM's design and development process
