This paper aims present information regarding Automotive Body in White (BIW) development fundamentals, providing a link between physics fundamentals and real automotive development. An introduction about product development process will be shown in order to allow the reader comprehension about timeline decision process.
A properly revision regarding applied loads, body in white materials, safety and virtual/physical validation will be covered. Structural fundamental knowledge has a key role of Design Engineer background mindset to achieve challenges vehicle targets about cost, mass and performance.
The paper information provides a clear technical reader understanding how product engineers use structural fundamental theories to design BIW in real design development application.
A study of case regarding Front-end tie-bar was used. A real vehicle load application was simulated by CAE analysis. The engineers analyzed the results and proposed design changes based on structural fundamentals. The final results presented a mass reduction of 9.2% achieving the stiffness target performance of 400 N/mm.
