Vibration Analysis: High-speed stereo DIC on
car door slamming

Case Description
Two procedures were adopted to introduce vibrations on a car door: via a shaker and through a manual human slam. Both events are imaged with 2 iX high–speed cam-eras. Accelerometers were simultaneously attached and Simcenter SCADAS system was invoked to impose per-fect synchronization between the accelerometers and the recorded images. An optimized DIC analysis was ob-tained using MatchID Stereo Correlation. Frequency re-sponse functions (FRF) could then seamlessly be extract-ed via a direct integration between Simcenter Testlab and MatchID. Finally, the corresponding operational de-flection shapes were determined, combining results from classical sensors and DIC.
