NVH Optimization Process in Powertrain Design Loop

This presentation will show how, at Renault, optimization procedures are used in powertrain design loop in order to meet NVH requirements. Insights on NVH powertrain theory will be presented and the translation of its issues into optimization constraints. Examples will illustrate how several procedures are consistently applied in the design process. A focus will be made on mounting bracket optimization with a different approach than using the MODETRACK tool. Studies on structural parts, crankshaft and acoustics will be presented.
