This paper investigates the use of conventional operational modal analysis (OMA)
techniques for modal parameters identification of a rotating system supported by roller …

The paper investigates the use of operational modal analysis (OMA) techniques applied
directly into a rotating machinery with hydrodynamic journal bearings. OMA has proven to be …

Rotating machines are an essential part of the majority of the power plants. They have to be
extremely reliable to avoid power outages, therefore, it is important to predict and monitor …

ABSTRACT Operational Modal Analysis has been widely used to extract and monitor modal
parameters of systems in operation. There is a great number of research in which OMA was …

The problems addressed in this paper are related to the dynamic characterization of
structures that have their operational response dominated by rotating components. This is …

In recent years, modal analysis has become one of the essential methods for modification
and optimization of dynamic characteristics of engineering structures. This is the first …

Many parameters can be used to express a machine's condition and to track its evolution
through time, such as modal parameters extracted from vibration signals. Operational Modal …

Industrial machinery is often equipped with proximity probes that measure continuously
position and vibrations of the shaft, generally relative to the bearings. These measurements …

Abstract The Order-Based Modal Analysis (OBMA) technique shows to be very powerful for
identifying the modal parameters in operational conditions in case of rotating machineries …

Modal analysis techniques are widely used to characterize vibrations in structures, vehicles,
machinery, etc. Modal parameters obtained through modal analysis are useful for structural …
