Abstract
Operational Modal Analysis (OMA) method is very often used for the identification of mechanical parameters of engineering structures. This method can be applied under the assumption that the excitation acting on the tested system is random. This requirement is not met in case of some industrial machines (e.g. in power engineering) while the excitation related to rotating elements significantly worsen the accuracy of modal models estimated by means of the OMA methods. Therefore the methods making it possible to overcome this problem arise great interest. One of such methods is OMAX that nowadays is more and more frequently applied to operational identification of mechanical structures. The paper concerns comparison of the classical methods (OMA) and OMAX method. The results were verified experimentally for the characteristics measured on the laboratory object and on the wind turbine. © JVE International Ltd.
