Improvement of NV Performance for Automatic Transmission Using Large Scale Optimization 2008-01-0869

A design process to improve noise and vibration (NV) performance for automatic transmissions of vehicles is presented. The proposed process uses a newly developed large-scale optimization technique to solve large-scale analysis problems. Additionally, useful and/or necessary techniques including Topometry optimization, beta method and modal contributions are described and used to solve modal dynamic optimizations. As a demonstrative problem, the process is successfully applied to improve the NV performance of the AISIN AW FWD automatic transmission.
