Modal Analysis
The Modal Analysis package within m+p Analyzer delivers a comprehensive solution for understanding, analyzing, and validating the dynamic behavior of mechanical structures.
Designed for both laboratory and field environments, it enables engineers to accurately evaluate natural frequencies, damping characteristics, and mode shapes—critical for optimizing product performance and structural integrity.
The platform supports a full range of methodologies, including:
- Experimental Modal Analysis (EMA)
- Operational Modal Analysis (OMA)
- ODS (Operating Deflection Shape)
- SDOF & MDOF Analysis
- SIMO & MIMO Shaker Testing
- Modal Model Validation & FE Correlation
APPLICATION AREAS
- Automotive, Aerospace & Defence structural dynamics
- Experimental & operational modal analysis
- Ground vibration testing (GVT)
- Fixture design for MIL-STD-810 environmental testing
- Structural modification and troubleshooting
- FE model validation and updating
EXPERIMENTAL MODAL ANALYSIS (EMA)
The system simplifies geometry creation, measurement, and modal parameter extraction:
- Easy creation or import of test geometries (UNV/UFF, STL, CAD)
- Automatic calculation of frequency, damping, and mode shapes
- FRF-based curve fitting for accurate modal parameter estimation
- Import/export of data from multiple measurement systems
Advanced tools support Structural Dynamics Modification (SDM) and FE model correlation, enabling accurate comparison between test and simulation data.
INTELLIGENT & WIZARD-GUIDED ANALYSIS
Built-in analysis wizards streamline the entire workflow:
- Step-by-step guidance for data acquisition and analysis
- Intelligent estimation of analysis parameters
- Advanced handling of closely spaced and repeated modes (MDOF)
This ensures reliable results for both novice and expert users.
ADVANCED DATA INTERPRETATION
The system utilizes state-of-the-art algorithms for clear and accurate results:
- p-LSCF (Polyreference Frequency Domain) for highly damped structures
- PTD+ (Polyreference Time Domain Plus) for lightly damped systems
These algorithms generate highly stable and interpretable stabilization diagrams, even for complex, high-order systems.
GROUND VIBRATION TESTING (GVT)
For Aerospace and large structural systems, the platform supports advanced Ground Vibration Testing:
- Multi-shaker Normal Mode Tuning
- Real-time visualization of mode shapes and MIF (Mode Indicator Function)
- Optimized excitation for accurate modal isolation
- Stepped sine analysis for detailed mode investigation
