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 via a manual human slam. Both events were filmed with two high-speed iX cameras. Accelerometers were attached simultaneously and the Simcenter SCADAS system was invoked to enforce perfect synchronization between the accelerometers and the recorded images. An optimized DIC analysis was obtained using MatchID stereo correlation. Frequency response functions (FRFs) could then be extracted seamlessly through a direct integration between Simcenter Testlab and MatchID. Finally, the corresponding operational deflection shapes were determined, combining the results from the conventional sensors and MatchID.
