Structural Vibration Solutions DEWESoft ARTeMIS Modal Pro v7.2.2.4

This is the basic version of ARTeMIS Modal having a frequency domain method for Operational Modal Analysis, and optionally direct data acquisition support and frequency domain methods for Experimental Modal Analysis. It is the software that allows you to get both modal analysis and operating deflection shapes analysis at a favorable entry price. The software includes setup tasks allowing you to create a project from scratch. There is a geometry generator where test geometries can be made in an object oriented manner, or you can upload gerometries into the software from various popular file formats. Measurements for Operational Modal Analysis and Operating Defection Shapes analysis can be loaded from more than 20 different file formats. Measurements channels can be assigned to the right geometry nodes and directions using drag and drop features. The software has a variety of built-in signal processing tools that can be used to enhance the performance of the analysis methods. In the basic version there are tools for detrending, decimation and filtering of the raw data as well as spectral density estimation. There is alsp an automatic selection of the so-called projection channels for more effective processing. The basic version has the effective Frequency Domain Decomposition (FDD) method for Operational Modal Analysis. There are various validation features available, such as mode shape animation and the Modal Assurance Criterion. In addition, it has time and frequency domain Operating Deflection Shapes analysis. It also comes with a built-in report generator which allow you to produce predefined reports in Microsoft Word and Microsoft Power Point. The basic version seamlessly integrates with the Direct Hardware Control, and Experimental Modal Analysis plugins. This opens up for direct measurements for Operational Modal Analysis as well as e.g. direct impact testing for Experimental Modal Analysis.

Standard is the mid-size version of ARTeMIS Modal that, besides all the tasks and features of the basic version, also includes additional frequency domain methods for Operational Modal Analysis and more validation features. This version includes signal processing for detection of harmonic peaks in the spectrum. Harmonic peaks are caused by the presence of rotating components during measurements of a structure. During operational modal analysis of rotating machinery, it is important to be able to distinguish peaks of structural modes from peaks caused by the excitation. Two additional Frequency Domain Decomposition methods are available, that can estimate mode shapes and natural frequencies with more accuracy. On top, these methods also provide an estimate of the damping ratios. Modal parameters from the three built-in modal estimators can be validated against each other in a special designed validation task. In addition, modes obtained from external tools can be imported through Universal File Format and validated against internally produced results. The Standard version seamlessly integrates with the Direct Hardware Control and Experimental Modal Analysis plugins.

In addition to all features and tasks of the Basic and Standard versions, this version has up to five different time domain methods for Operational Modal Analysis. The methods are all of the very fast en efficient Crystal Clear Stochastic Subspace Identification (CC-SSI) type. These methods estimate the modal parameters directly from the measured time series, and some methods even estimate the uncertainties of the modal parameters. This version also includes effective peak reduction techniques, that can be used for pre-processing of the measurements. It can effectively remove selected peaks that can be e-g. servere harmonic peaks caused by the presence of rotating components during measurements of a structure. The Pro version seamlessly integrates with the Direct Hardware Control and Experimental Modal Analysis plugins. It also integrates with the Structural Health Monitoring plugins for Damage Detection, Modal Parameter History tracking and Interstory Drift Analysis. An Automatic File Upload plugin is also available. With this plugin, files being dumped in a designated folder will automatically be uploaded and processed by the software. In this way, modal parameter estimation and damage detection can be performed automatically with user interaction.
