Automotive industry is undergoing major structural changes and by the year 2010, there would be five to eight OEMs and significantly reduced number of 1 S1 tier suppliers, providing at OEMs production line assembled systems and modules. This restructuring; pressure upon cost and time-to-market; and increased customers expectation upon quality, especially for NVH, has put a quite new set of requirements upon the vehicle development tools. MSC.visualNastran is an integrated product and process development tool, both for the OEMs and the suppliers to meet the above mentioned challenge. Using this tool, the body shell structure and the various vehicle modules and systems from 1 st tier suppliers can be optimised. The sound deadening material for the interior can be designed effectively using coupled acoustic approach. The total vehicle system can be tuned for various NVH-requirements. (A)
