Modal Shape Visualization Employing FP + 2D-DIC and Phased-Based Motion Magnification

Blog Article

Recently, the combination of Fringe Projection (FP) and 2D Digital Image Correlation (2D-DIC) has become a low-cost alternative for measuring deformations even in dynamic events such as vibration testing.FP and DIC are displacement measurement techniques, so high frequency vibration tests iPhone 7/8 associated with low levels of displacement suppose a challenge.By means of Phase-Based Motion Magnification algorithm (PBMM), the periodic displacement observed in an image sequence can be magnified.

This makes it possible to measure clear displacement maps by FP WHOLY TEA ORIGINAL + 2D-DIC even when subtle displacement occurs.This methodology allows a better interpretation of the vibration behavior of mechanical components.In this work, the behavior of a beam excited at its natural frequencies has been studied, showing the potential of PBMM and FP + 2D-DIC.
