Determinação da velocidade de impacto a partir da análise da energia de deformação acumulada

Abstract

Vehicle accident reconstruction is an essential discipline aimed at under- standing critical details of collisions, such as vehicle speed at the moment of impact. The primary goal of this study is to determine vehicle collision speed through the analysis of frontal deformation observed post-impact. The methodology integrates modern techniques, including photogrammetry to create detailed three-dimensional damage models, LiDAR-based 3D scanning, and numerical simulations through finite element modeling (FEM). The obtained results demonstrated reduced error margins in speed estimation, confirming the accuracy and effectiveness of the adopted methods. Qualitatively, the proposed methodology proved robust and reliable across different real-world collision scenarios, highlighting its significance in forensic analysis and automotive safety. The study concludes that the developed method represents a reliable technical tool for forensic investigations, significantly advancing automotive safety and the scientific understanding of vehicle collision phenomena.
