Weight Optimization of BIW

Weight Optimization of BIW
  • MDO (Multi-Disciplinary Optimization) of the BIW for Mass reduction is done through MMO (Multi Model Optimization) approach considering the stiffness, modal analysis and vibration aspects.
  • Following Load cases are considered : (1) Static stiffness which includes Torsional and Lateral Stiffness (2) Frequency Response Function Analysis at the hard points like engine mounts and suspension attachment locations on BIW.
  • For torsional stiffness optimization, the translational displacements are calculated at 8 nodes along front and rear end of the vehicle on both sides.
