Abstract [en]

Producing simulated test data from models of mechanical structures is often important for validation of analysis methods, for example parameter identification methods. Whereas investigations of test procedures and identification methods for operational modal analysis (OMA) are widely reported based on simulations, little attention is often given to the actual procedures to produce simulated response signals. For example the influence of the excitation strategy in a simulation on the following identified properties. In the present work different excitation strategies are applied to simulate responses of a modal model of a Plexiglas plate. OMA parameter identification is performed on the simulated responses and the results are compared to see the influence of chosen excitation strategy. Furthermore OMA results from a lab measurement of the real physical Plexiglas plate are presented and compared to the simulation results.
