[Shape Optimization Example] Optimization of Reinforcement Rib Shape for Automotive Parts

It is possible to easily parameterize shape changes! The height of the reinforcing rib is prepared using a model in its initial state.

We will introduce a case of shape optimization for reinforcement ribs using "LS-DYNA" and the optimization support tool "Altair HyperStudy." The height of the reinforcement ribs was optimized by preparing a model in its initial state and morphing the shape from the lower limit to the upper limit. A model was prepared for the maximum number of ribs (minimum pitch) and then morphed to achieve the minimum number of ribs (maximum pitch). As a result, since GRSM explores globally compared to ARSM, suitable shapes that meet the constraint conditions are obtained even when the plate thickness on the long side of the rib is small. 【Analysis Model】 ■ Shell elements (mesh size 10mm) ■ Elastic material ・ Young's modulus: 2000MPa ・ Density: 1.1×10^-9 ton/mm³ ・ Poisson's ratio: 0.35 *For more details, please refer to the related links or feel free to contact us.
