X-Ray Automotive Crash Monitoring
Challenges of System-Level X-Ray Crash Monitoring:
- To increase safety and optimize material selection, information about structural deformation during automotive crash is required not only on exterior surfaces but also within the interior.
- Despite highly developed numerical simulation tools, dynamic deformation paths of complex structures are often hard to predict.
- Automotive crash is a highly dynamic process occurring on short timescales. There is not enough time to perform conventional X-Ray Computer Tomography and 3D reconstruction. New specific X-Ray methods need to be developed for this dynamic application.
Tasks for Sustainable Systems Engineers:
- Develop integrated approaches which combine both numerical simulation and real X-Ray volumetric data to yield highly detailed information about the fast deformation paths.
- Investigate material substitution possibilities to meet sustainability challenges while maintaining crash safety.
Related scientific projects at INATECH:
INATECH scientists at Fraunhofer EMI developed dynamic X-Ray based monitoring capabilities for in-situ observation of crash tests. Specialized reconstruction algorithms identify relevant deformation processes occurring on time scales of 100 µs. The initial work was funded as part of the FhG-MAVO fastCrash project.
