- Body in White (BIW) torsional stiffness is an important parameter for passenger vehicles, influencing its behavior regarding Noise, Vibration & Harshness (NVH), durability and handling. A BIW with high stiffness may impact mass and cost since it would be necessary to add reinforcements and/or increase thickness of the panels with more contribution for this parameter.An OEM (Original Equipment Manufacturer) may have to choose an existing platform to continue a particular vehicle family and this decision will be based on mass and costs. This work aims to study a relationship between mass and stiffness of some platforms, trying to give an auxiliary parameter to help in the OEM's decision, differentiating the stiffness of the lower (platform) and upper body.
