Experimental Modal Analysis / Structural Dynamics Testing

m+p SO Analyzer is a fully integrated solution for measurement, analysis and advanced reporting of all your noise and vibration, acoustics and general dynamic signal applications.

m+p SO Analyzer’s structural dynamics package provides a complete set of tools for observing, analyzing and documenting the vibrational behaviour of machines and mechanical structures. Different software modules cover a wide range of techniques including impact testing, shaker
measurements (SIMO and MIMO), experimental and operational modal analysis, modes of vibration animation, modal model validation and ground vibration testing.

The standard structural dynamics package includes:

• Impact testing using a modal hammer
• Creation of component-based geometries
• Operating Deflection Shape (ODS) analysis

Optional software modules are available to cover the most demanding and advanced modal analysis applications:

• Single Degree of Freedom (SDOF) analysis
• Multiple Degree of Freedom (MDOF) analysis
• Circle fit wizard to review and validate FRF data and mode shapes (experimental modal analysis)
• Operational modal analysis (OMA)
• Modal model validation (MAC, MPD, MPC, MOV, MIF)
• Polyreference Time Domain algorithm (PTD/PolyTime)
• Polyreference Time Domain Plus algorithm (PTD+/Polytime+)
• Polyreference Least-Squares Complex Frequency domain algorithm (p-LSCF/Polyfreq)

The experimental modal data are obtained by curve fitting a set of Frequency Response Function (FRF) measurements. Wizards take you through a simple series of steps to complete the acquisition and analysis process and also make intelligent estimates of all analysis options. The Multiple Degree of Freedom (MDOF) wizard, for example, handles the most sophisticated modal analysis tasks, such as detecting repeated or closely spaced modes.
