Abstract

This paper deals with description of modification and using high-speed digital image correlation method in experimental modal analysis. In its theoretical part the basic principle of digital image correlation and description of modification of correlation system Q-450 Dantec Dynamics for the purposes of SIMO (Single Input / Multiple Output) assumption of modal parameters is introduced. The practical part – analysis of reliability of program Modan3D, developed for modal parameters estimation – was realized on a simple steel specimen in laboratory conditions. The obtained outputs are present in a form of graphs and tables.
