A design process to improve the structural performance under contact conditions of automatic transmission of vehicles is presented. The proposed process uses newly developed nonlinear contact optimization techniques. Additionally, useful structural optimization techniques such as 3D topography and the beta method are described. As a demonstrative problem, we consider the improvement of a 6- speed AISIN FWD automatic transmission which is subjected to static loadings and nonlinear contact conditions.

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.

A methodology to optimize sound pressure responses of a structure, producing a radiation noise due to structural vibration, is presented. The method involves a finite element analysis module to calculate structural vibration, an optimization module to perform sensitivity analysis and structural optimization, and an acoustic module to compute acoustic transfer vectors. The proposed design system is successfully implemented and is demonstrated in the paper using several example problems.
