Operational and Experimental Modal Analysis Software for Operational Modal Analysis (OMA)

Do you need to do modal analysis without controlling the input?. You might wonder what Operational Modal Analysis, OMA, is and how it differs from the traditional Experimental Modal Analysis (EMA) that has been around for the past few decades. Operational Modal Analysis is also called output-only modal analysis, ambient response analysis, ambient modal analysis, in-operation modal analysis, and natural input modal analysis.

Operational and Experimental Modal Analysis Software for Experimental Modal Analysis (EMA)

All versions of ARTeMIS Modal support classical modal analysis also known as Experimental Modal Analysis^.

Operational and Experimental Modal Analysis Software for Structural Health Monitoring (SHM)

Structural Health Monitoring – Do you need to test the integrity of a structure over time? ARTeMIS Modal Pro has a series of plugin modules designed for Structural Health Monitoring purposes. All modules are designed to analyse and present the health of a monitored structure in various manners, and they all rely on the same common data manager base module. This module administrates the recorded measurement files as well as the results obtained during a periodic monitoring.

Operational and Experimental Modal Analysis Software for Rotating Machinery Sector

There are different ways to handle the problems arising from the harmonic components in the vibration measurements.

Operational and Experimental Modal Analysis Software for Operating Deflection Shapes (ODS)

ARTeMIS Modal includes time as well as frequency domain Operating Deflection Shapes (ODS). These features allow you to study the overall vibration pattern either over a time segment or at a specific frequency. ODS analysis is very beneficial in combination with Operational Modal Analysis as it determines and visualizes the combination of the actual forcing functions acting on the structure and the dynamic behavior of the structure. Results can be shown as displacement, velocity or acceleration in SI, Imperial...

Operational and Experimental Modal Analysis Software for Direct Data Acquisition Control

ARTeMIS Modal now includes plugins that enable direct control of data acquisition modules. This allow recorded measurements to be directly saved into the active project.

Operational and Experimental Modal Analysis Software for Harmonic Detection and Removal (HDR)

All versions of ARTeMIS Modal support the Harmonic Detection and Removal (HDR) plugin that enables detection and possible removal of harmonic components present in the response measurements used for Operational Modal Analysis. In frequency domain, harmonic components can be seen as sharp peaks indicating the rotational frequencies and its possible multiples also called orders. The harmonic components can have a high level of energy compared to the modal response of the structure. This can seriously...

Operational and Experimental Modal Analysis Software for Civil Engineering Sector

Back in the 1980’s civil engineers were among the first to adapt Operational Modal Analysis (OMA) for testing of large structures. The size of the civil engineering structures and the fact that ambient excitation typically is uncontrollable pushed the development of OMA techniques heavily in this area. Today OMA is a wide spread technology used in many engineering field but testing of civil engineering structures is still the most popular OMA application. Back in 1999, ARTeMIS software was originally...
