VIC-Vibration Analysis

The VIC-3D Vibration Analysis System 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 on the right 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 on the left 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 on the left, with only 12 microns of displacement amplitude.

What is transient vibration analysis?

Transient vibration analysis is the process of monitoring, measuring, and analyzing the condition of samples during a transient event. Material properties can also be observed through the analysis of operational deflection shapes and mode shapes created by the event. These full-field 3D shapes can provide useful information which can be used to improve and correct a sample’s balance, displacement, flexure, rigidity, and overall product performance. Measuring operational deflection shapes can help answer the question: “How much is this structure actually moving at a particular frequency?”
