Vibration Analysis: High-Speed Stereo DIC on Car Door Slamming
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 two iX Cameras i-SPEED® 513 high-speed video cameras. Accelerometers were simultaneously attached and Simcenter SCADAS system was invoked to impose perfect synchronization between the accelerometers and the recorded images. An optimized DIC analysis was obtained using MatchID Stereo Correlation. Frequency response functions (FRF) could then seamlessly be extracted via a direct integration between Simcenter Testlab and MatchID. Finally, the corresponding operational deflection shapes were determined, combining results from classical sensors and DIC.
