[10] Rapid SEA Model Building Using Physical Measurements on Vehicles

The complexity of various CAE techniques for modeling NVH phenomena has long remained a difficulty for much of the Automotive Supply community. Complex details of Body Structures and Sound Packages are often not available outside of the OEM community and short program timing provides only a arrow window of opportunity to fine tune CAE models. This paper presents an efficient approach to build full vehicle Statistical Energy Analysis (SEA) models when no CAD/FEA data is available. The resulting model is then used to study the effects of changing the Transmission Loss characteristics of laminated glazing system components. Thereby providing a basis for verification of product performance within the vehicle as a whole, and as a foundation for the direction of future product development of glazing systems.
