Analysis of structural vibrations using time averaged shadow Moire

Abstract

The problem of bending vibrations is analysed in this paper. Shadow moire is one of the popular methods for experimental analysis of bending vibrations of structures. The time averaged shadow moire images of the eigenmodes of bending vibrations of a plate enable to quantitatively analyze the vibrations of the elements of printing devices and other structures. Shadow moire is one of the methods for experimental analysis of vibrations of the surface of the fluid. Time averaging for the analysis of vibrations according to the eigenmode is applied for this problem also. the images of the eigenmodes of the surface of the fluid are obtained.
