Good structural analysis starts with good data! For that reason, all the tools for efficient and accurate acquisition have been integrated into our structural solutions: state of the art analyzer technology and applied user interface.
Running through an impact hammer acquisition of modal data is made so much easier with the right tools.

As the first step, roving impact hammer techniques or shaker excitation (SIMO, MIMO) acquisition require specific displays, functions and monitoring. The FFT mode let you acquire structural properties featuring high dynamics range, automatic node increment, direct control of weighted force and response signals, averaged FRF and coherence preview.
For shaker excitation and high channel count on large structures, OROS VibeMaster include advanced sweep/step sinus, noise generation, associated with a full cross-spectra matrix computation.

The goal of troubleshooting and diagnostic operations is to detect vibrations level, main cause of damage on machinery. The critical step is the source identification among the variety of possible origins. That is why the diversity and complementarity of field oriented OROS products’ range are great advantages in this domain. OROS Modal 2 provides direct acquisition and powerful Operating Deflection Shape to identify high structural coupling with the machinery and its foundation. Regarding high excitation due to unbalance, misalignment or instabilities, ORBIGate®, Balancing, or NVGate® will help the user in his diagnostic.

Industrial machinery must be permanently improved and optimized to answer to competition and cost constraints. Development departments always seek for the best quality and performances and try to minimize the costs of production and maintenance. A comprehensive set of tools is necessary to take up this challenge, especially compatible simulation and experimental software. OROS Modal 2 offers up-to-date algorithms for Experimental Modal Analysis implemented in an open interface. The calculated modal parameters can easily be exported to software like FEMtools, which provide correlation and model updating modules.
