Researchers have developed a novel framework using region-aware graph neural networks for robust and explainable 3D mode shape recognition in automotive NVH development. This approach transforms heterogeneous engineering data into a common graph representation, decoupling engineering knowledge from numerical discretization. The method has been validated on datasets from four vehicle programs, demonstrating high accuracy, cross-vehicle transferability, and physically meaningful explanations tied to structural regions. AI
IMPACT This new framework could improve the efficiency and accuracy of automotive NVH development by automating mode shape recognition and providing interpretable results.
