WebThe main objective of this project is to estimate the bending and torsional stiffness of a BIW using Hyper Mesh. Suggestions are made to increase the bending stiffness and torsional stiffness by 5%. WebFeb 8, 2024 · The joints in the BIW are parametrized and Altair Optistruct [1] tool is used to find optimum value of each parameter. The contribution of different joints to the overall stiffness is different for different loads. This methodology was applied to a simplified BIW model for a combination of two load cases-static torsion and bending.
