Abstract
A design process to reduce mass and sound pressure for automatic transmissions of vehicles is presented. The proposed process uses a newly developed topography optimization technique. Additionally, useful and necessary techniques including sound pressure optimization and the beta method are described. As a demonstrative problem, the design process is successfully applied to reduce mass and sound pressure of a 6 speed AISIN AW FWD automatic transmission.
