Main features

• Geometry Building
  Interactive interface to create, modify, assemble standard elements or complex structure with global and local coordinate systems. Import from external software in universal file format.
• Direct acquisition & Signal processing
  Dedicated interface for modal acquisition with impact hammer, shakers or under operational conditions to obtain:
  • FRF H1, FRF H2 for EMA
  • Power Spectral Density, Half Power Spectral Density for OMA
• Operating Deflection Shape (ODS)
  ODS is a great tool to visualize dynamically the vibration deflection shape of mechanical components during their normal operation.
  It offers rapid visual feedback on the deformation of a structure in both time and frequency domain.
• Experimental Modal Analysis (EMA)
  Using an impact hammer or shaker(s), several identification methods allow one to determine modal parameters: frequency, damping and mode shape. Users can perform Single Input/Multiple Output (SIMO) method for a first approach and Multiple Input/Multiple Output (MIMO) techniques to make a more thorough analysis.
• Operational Modal Analysis (OMA)
  OMA is a very interesting technique for large structures or test items that are not easily excitable (e.g., civil infrastructures). With this method, modal parameters can be estimated without a known, controllable excitation signal.
• Validation
  Modal Assurance Criterion to compare modal parameters from different methods. It’s compatible with external results from experiment and simulation.
