ARTeMIS Modal is an open, and user-friendly platform for modal testing, modal analysis and modal problem solving. If you can measure the vibrations, ARTeMIS Modal can give you the modes in terms of mode shape, natural frequency and damping ratio. For two decades ARTeMIS Modal has been the preferred software for Operational Modal Analysis (OMA).

Software for Operational Modal Analysis and Experimental Modal Analysis
The modal analysis technology for the vast number of cases where it is preferred not to control or measure the loading. Now all versions of ARTeMIS Modal also includes polyreference methods for Experimental Modal Analysis (EMA).

Operational Modal Analysis
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. No matter the name, the idea is the same: Conduct a modal analysis without knowing and/or controlling the input excitation. This modal technology is capable of estimating the same modal parameters as the traditional known techniques.
Experimental Modal Analysis
All versions of ARTeMIS Modal support classical modal analysis also known as Experimental Modal Analysis1.
FRF's can be uploaded using Universal File Format (UFF/UNV), or be internal estimated by uploading input and output time domain measurements in the Manage Measurement Task, or by using the Impact Testing Module2.
Structural Health Monitoring
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.
Operating Deflection Shapes
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 or user-defined units. Decimation and various filters (low-pass, band-pass, band-stop and high-pass) can be applied to frequency limit the analysis.
Both time and frequency domain ODS are available in all versions of ARTeMIS Modal.
