Operational Modal Analysis (OMA) is used to identify the dynamic properties of structures such as natural frequencies, damping rations, and mode shapes based on vibration measurements collected under ambient or operational excitation.
OMA is particularly useful for structures where the controlled excitation is impractical or impossible.
Operational Modal Analysis is widely used in structural dynamics and Structural Health Monitoring.
Typical applications include:
OMA is preferred in these scenarios because it:
In many engineering applications, vibration measurements are used to track changes in modal parameters over time.
These changes can indicate:
Such analyses are typically performed using specialized OMA software tools.
OMA applications rely on software capable of processing vibration data and extracting modal parameters. These capabilities are implemented in tools such as ARTeMIS Modal Pro, which supports modal identification, validation, and visualization for a wide range of structures.
