Numerical-Experimental Approach for Simplified Aerospace Structures’ Testing Using the Eulerian Video Magnification Technique

This study presents a low-cost, non-contact experimental approach for structural dynamic testing of simplified aerospace components using Eulerian Video Magnification (EVM). Vibrations induced by a shaker are captured at 120 frames per second (fps), processed through a custom Python EVM algorithm, and compared with Finite Element (FEM) and analytical models. Results showed frequency deviations below 2% between EVM and FEM, validating the method’s accuracy. The approach demonstrates that meaningful modal data can be obtained with consumer-grade equipment, enabling affordable, accessible, and non-invasive modal analysis for aerospace applications
