#16617–FFT with DIC: Improvements in Data Processing and Vibration Visualization
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.
