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.
EXPERIMENT SETUP
Cameras: 2 iX Cameras i-SPEED 513, 6,382 fps @ 1920 x 1080 resolution

ANALYSIS
Type: Stereo DIC with optimized settings
Vibration: Modal parameters identified with Simcenter Polymax
Mode Shapes: Deflection shape determination with MatchID ODS Module
RESULTS
Stereo DIC: Time resolved displacements results
Natural frequencies: structural resonances & damping
Operational Deflection Shapes: 3D deformation at the identified natural frequencies
