Opis:: Vibration analysis has found widespread application for condition monitoring in a variety of applications and industries. With the continual development of cheaper and more powerful processing hardware, such systems have developed from utilizing simple checks on amplitude to those based around sophisticated spectral analysis. The paper presents application of the model based diagnostic method for early detection of faults in rotating machinery. The proposed diagnostics system based on modal analysis methods (OMA and OMAX methods). In the paper the diagnostic system based on such modelling is presented. The proposed system was verified during research on a specialized test rig, which can generate vibration signals.

Opis:: Modal analysis allows to determine natural frequencies, modal damping ratios and mode shapes of mechanical structures. This paper presents a case study of application of the operational modal analysis to testing of a bridge during its normal service. The main purpose of the research was to determine the natural frequencies and mode shapes for the purpose of assessment of the bridge’s truss condition. In the paper a method of verification of the recorded measurement data quality as well as results of estimation of modal parameters are presented. The results of the carried out investigations were used by the manager of the bridge to plan the bridge truss’ renovation.
