The Vic-3D™ Vibration Analysis system by Correlated Solutions, Inc. is a new addition to the Vic-3D product line of measurement solutions. Vic-3D Vibration enables full-field 3D viewing, measurement, and analysis of transient events. Full-field operational deflection shapes in the frequency domain can easily be seen and compared with levels of accuracy in the nanometer range.
The image above on the left is a mounted model jet plane which has undergone a transient vibration event. To the right, the 3D vibration data obtained from the event is shown as a 2D contour overlay on this image. The data overlay enables the user to see exactly how much deformation is occurring and where it is occurring. This information is available at each frequency where deflection shapes occur.
The data below displays one operational deflection shape obtained with the VIC-3D™ Vibration Analysis System. Three-dimensional displacements, strains, velocities, and accelerations can all be computed in the analysis software. The result is not only visual, but also enables the user to export quantitative data (ASCII, MatLab, CSV, etc.) from the sample’s behavior for FEA analysis and validation. A 3D animation of the model jet’s operational deflection shape at 441 Hz is shown below, with only 12 microns of displacement amplitude.
