ZASTOSOWANIE EKSPERYMENTALNEJ ANALIZY MODALNEJ W OCENIE ZMIAN SZTYWNOŚCI PROSTEGO ELEMENTU KONSTRUKCYJNEGO.

Modal methods are classified among the methods of condition monitoring as a global method. Their main characteristic is that they allow only the determination of the status of airworthiness design without the ability to accurately locate the fault. This paper present use of experimental modal analysis to assess changes in the stiffness of the simple component and verified possibilities of this method to accurately locate the fault.
