Paper Abstract
The solution of structural-acoustic problems in vehicle development needs improvement of calculation and experimental dynamic analysis methods. In this aim, new analysis methods based on 1-D and 3-D displacement measurements recorded by pulsed holographic interferometry have been developed. These essentially allow to perform 3-D finite-element model updating, improvement of physical understanding for particular vibration phenomena and analysis of dynamic responses in running conditions. We discuss, in particular, two different original methods which make possible to determine the modal participations in a dynamic response measured in non-steady state conditions. Several research and industrial measurement applications are presented.
