Abstract
The paper deals with an issue that car researchers are facing increasingly more, related with how to virtually shape in specific software programs, the existing parts of interest from an real automotive body frame, in order to modify their digitized dimensions and afterwards optimized their design process to sustain real environment challenges, after virtual soft tuning impact with the programmed drag stress, knowing that over the speed of 120km/h more than 60% of engine power is used to face aerodynamic forces.
Keywords: automotive body frame, pressure, drag force, virtual environment simulation, modal analysis.
