Vibration Analysis: High-Speed Stereo DIC on a Drying Machine

Case Description
Two procedures were adopted to introduce vibrations on a drying machine: via a shaker and within operational conditions. 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 solution 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.
