Abstract
Reduced model based on Proper Orthogonal Decomposition (POD) was established from FE sampled results in IIHS SUV side impact, and displacement modes of center pillar were reconstructed. Displacement reconstructed by the reduced model showed good correlations with results by FE models in case of changing length or thickness of center pillar parts, and the max displacements of center pillar were predicted within 6.2% errors of FE results in a few seconds. Variations of displacements mode of center pillar also were investigated by reduced model based on POD.
