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 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. 

EXPERIMENT SETUP

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

Validation: Accelerometers & Simcenter SCADAS

Acquisition Speed: 1,600 Hz 

 

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
