Crash Analysis

Crash analysis is an integral part of safety analysis and is often completed at intersections and corridors. The crash analysis can help assess concerns and help determine potential improvement options. A 3D inspection software supports this activity, some of them make use of advanced databases on vehicle dynamics built over years of crash tests and simulations and make use of laser scan inputs. By reconstructing a 3D model of the vehicles after the crash it is possible to precisely measure deformations and the impact. Initially, in the reverse engineering software, the two sets of scan data and CAD data were overlaid and compared to see if the crushed areas conformed to design expectations. Sometimes anomalies and variations occur in vehicles as was the case in a fatal accident involving the same model. The undamaged car provided baseline geometry and the crash-tested pattern of crush. These data sets were overlaid on the scan from the accident vehicle to compare the complete geometry. The inspection report will be generated and output data is given in the desired format.
