Topology and Frequency Response Function Analysis Applied to Structural Parts Aiming Mass and Cost Reduction
In the vehicle development, part design has a huge influence in its mass, cost and performance. In addition, the part design can be helpful to solve some structure issues such as sheet metal cracks and boom noise, and at the same time achieving the project requirements in performance tests as crash, durability, noise and vibration (N&V) etc. Some design changes as adding reinforcements in the structure and increase the part thickness are largely used by the design engineers. On the other hand, these changes has a great potential for increase mass, cost and affect directly the fuel consumption, which are very sensitive factors for the OEM′s. In order to achieve its target some options may be considered like the use of aluminum or premium material such as Advance High Strength Steel (AHSS) or Pre Hardened Steel (PHS), which has a high cost considering the common sheet metal used in the vehicle structures.
