Correlated Solutions @ IMAC - XLII
‘Standing on the Shoulders of Giants’
January 29 - February 1, 2024 / Rosen Plaza Hotel, Orlando, FL
We are very excited to be heading back to Orlando next week for another installment of IMAC - a conference and exposition focusing on structural dynamics which has evolved to encompass the latest technologies supporting structural dynamics. Our team will give two presentations (details below), and we’ll be at Booth #211 to answer all your DIC questions. We’re looking forward to seeing old friends and making new connections while discussing all things Digital Image Correlation! We hope to see you there!
Technology Session #16617
VIC-3D HS FFT is a three-axis, non-contact, full-field measurement system that measures the amplitudes and phase changes of operational deflection shapes (ODSs) in the frequency domain using the Digital Image Correlation method.
Vibration measurements to obtain ODSs generally require thousands of image pairs to be analyzed per test, which may take upwards of one or more hours to process, depending on the efficiency of the source code. This talk will explain a new method that stores image files in a way that improves the speed of the DIC algorithms, decreasing processing time, without altering the images in any way.
Animating the in-plane and out-of-plane ODS’ components is not a trivial task, because this generally requires two-dimensional (in-plane) amplitudes to be displayed as an exaggeration within the image or in the 3D environment in order to visualize the behavior of the vibration. Moving the collected data to a dedicated workspace within the program allows the user to easily visualize and understand the behavior of the ODS. An overview of the new workspace will be explained using example data.
New/Young Engineer DIC Tutorial
This Digital Image Correlation Vibration Analysis tutorial will provide attendees with the basic principles of theory and testing methods of digital image correlation and how they apply to vibration analysis applications. First, the underlying principles for both two-dimensional (2D) and three-dimensional (3D) digital image correlation will be presented, then attendees will be shown how to perform a typical 3D transient vibration test and analyze the results in VIC-3D.
Individuals interested in full-field, non-contacting vibration, shape, and deformation measurement methods are encouraged to attend. This material does not require background knowledge of either 2D or 3D digital image correlation.
