3. Experimental modal analysis techniques
3.1 Objectives of experimental modal analysis
The aim of experimental modal analysis is to identify the modal parameters of a structure from dynamic tests, which involves :
determining the number of modes present in an analysis frequency band;
-
for each mode :
the evaluation of the complex natural pulsation s ν = - a ν ω ν + jω ν ,
determination of the associated normalized complex eigenvector d...
