Review of Saturn's Powertrain Analysis Methodology

An overview of the analytical engineering used to support the development of the new Saturn 1.9L powertrains is presented.

Computer-based techniques were used extensively throughout the program to predict performance and boundary data and to complete finite element and other computational. analyses to support design decisions. This work contributed to significant design modifications to attain durability goals in a severe test environment while attaining aggressive low mass goals.

A summary and recommendations are included to identify how advanced modeling techniques should be integrated into future engine programs to attain optimum designs and cost benefits with reduced program timing.
