Ad-Hoc Algorithm for Direct Data Processing on Board Each Single Node in the Structural Health Monitoring

In this work, the test of a new algorithm for the individuation of the modal frequency of a structure is presented. Its novelty is in the fact that the processing of the data, detected by the accelerometers, takes place directly on board of the single node. The test has been conducted on a metal bar whose modal frequencies had already been determined and taken as a reference. Then, the bar frequencies have been calculated using a new algorithm here presented. The result is the substantial correspondence between the reference frequencies and those calculated. Subsequently, the algorithm has been applied to a real structure.
