Structural model adjustment using iterative methods

摘要

This paper reports a procedure for adjusting structural theoretical models to experimental results based on optimization techniques. It also covers some of the basic concepts of correlation techniques that are normally used to correlate natural frequencies and vibration modes. The developed method is tested performing some numerical simulations with imposed anomalies and through dynamic experimental tests in a simple supported beam. The obtained results show it can be an excellent tool for adjusting structural models and possibly for damage detection using the first vibration modes.
