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 2 iX high–speed cameras. Accelerometers were simultaneously attached and Simcenter SCADAS system was invoked to impose perfect synchronization between the accelerom-eters and the recorded images. An optimized DIC solu-tion was obtained using MatchID Stereo Correlation. Frequency response functions (FRF) could then seamless-ly be extracted via a direct integration between Simcenter Testlab and MatchID. Finally, the correspond-ing operational deflection shapes were determined, combining results from classical sensors and DIC.
