Abstract: A mesh modification approach based on morphing technology was developed to address the challenge of fast re-analysis of modified structures without the need of changing the CAD model. The approach enables the evaluation of design concepts starting from the morphed predecessor models, allowing validated solutions to be incorporated in the first version of the CAD model. Different styling variants can be rapidly evaluated, matching the development time and cost constraints of OEMs. This article discusses the basic methodology by automotive example cases, and then focuses on full vehicle morphing techniques for NVH and crash analysis in the context of control-based morphing.

Keywords: concept phase; mesh morphing; vehicle development; vehicle design; CAD; styling variants; conceptual design; cost constraints; automotive NVH; noise; vibration; harshness; crash analysis.
