Abstract :

Structural dynamics model updating has been defined as the adjustment of an existing analytical model using experimental data so that the model reflects the dynamic behavior of the structure more accurately. The aim of the present study was to develop a MATLAB program for FRF based updating structural dynamics models. Analytically generated test cases and experimental data for the 5-DOF lumped parameter system showed that the RFM can locate modeling errors in the realistic case of noisy and incomplete experimental data.
