Abstract

The Proper Orthogonal Decomposition (POD) method is applied to the vibrations analysis of a metal plate. The data obtained from the metal plate under vibrations were measured with a laser vibrometer and Fringe projection technique. The metal plate was subject to vibrations with an electrodynamical shaker in a range of frequencies from 100 to 5000 Hz. The vertical velocity displacement measurements were taken on a quarter of the plate in a rectangular grid of 7 x 8 points using a Laser Vibrometer. The plate vibration measurements were used to calculate the eigenfunctions and the eigenvalues. It was found that a large fraction of the total energy of the vibration is contained within the two first POD modes. The essential features of the deformation are thus described by only the two first eigenfunctions.
