Abstract

Un attuatore generatore di forza collegato su oppure attraverso i punti di una struttura capace di movimento relativo con una frequenza di eccitazione viene fatto funzionare in modo da introdurre un predeterminato carico in ingresso nella struttura e quindi la risposta della struttura viene misurata per l'analisi. In una forma di realizzazione dell'invenzione, l'attuatore è uno di una pluralità di attuatori di un sistema attivo di controllo delle vibrazioni il quale viene isolato e fatto funzionare indipendentemente in un modo di collaudo allo scuotimento. Vantaggiosamente, specialmente nell'applicazione in un elicottero, i restanti attuatori possono continuare ad essere fatti funzionare per ridurre la vibrazione di fondo.
