Abstract
The vehicle development process demands quick evaluation of new designs. CAE and CAD tools are essential in order to perform these assessments in a very narrow time frame. New design variants with desired criteria should be quickly created and analyzed. Geometry based topology and shape optimization can accelerate such a process when changes in body structure are automatically updated. FE mesh generation during topology and shape optimization runs should not require any kind of user intervention. The above mentioned requirements are fulfilled by SFE CONCEPT™. This paper describes the feasibility of a vehicle development process where geometry modifications lead to a reduction for the interior noise of a full-trimmed car body model. In order to demonstrate this, a vibro-acoustic optimization is carried out for types of bead patterns in the BIW.
