Platform
Understand dynamics through modal shapes.
The Operational Modal Analysis (OMA) Tool computes the dynamic response of structures using wired, star-topology accelerometers. Utilizing the 4G Gateway to achieve millisecond-level time synchronization across the entire serial bus, the platform extracts modal frequencies and vibration modes with unprecedented phase accuracy.
First Torsional Mode
3D Deformation Profiles.
Based on millisecond-synchronized acceleration data collected over a hardwired star-topology network, the platform reconstructs the dynamic deformation profile of the structure for each modal frequency detected.
This representation enables engineers to assess how different parts of the structure move together or decouple under dynamic excitation.
Apply user-defined tags to filter sensor subgroups and isolate specific structural segments, distinguishing local anomalies from global responses.

Spatial 3D Displacement Pattern
Computed from the relative motion of the accelerometers used in the analysis. Resolves down to millimeter precision across the entire structure.
Structural Outputs
Processes synchronized acceleration data to compute and visualize structural response indicators across all axes.
Frequency Overview (X,Y,Z)
Visual summary of all modal frequencies detected across longitudinal, transversal, and vertical directions—displayed per axis and per sensor group.
Frequency Statistics
Modal frequency distribution across the sensor group. Highlights dominant modes, consistency, and deviation patterns for comparative structural analysis.
Frequency Trend Over Time
Track how specific modal frequencies evolve throughout different campaigns, allowing correlation with structural interventions or evolving degradation.
Modal Shape 3D View
Visualizes the full 3D modal shape for each detected mode—reconstructed by combining data from all sensors in the network.
Modal Shape 2D Slices
Displacement profiles of each modal shape, separated by axis: longitudinal, transversal, and vertical. Useful for isolating directional behaviors.
Displacement Trend by Shape
Displays the displacement of structural movement associated with each modal shape over time, helping identify mode-dependent stiffness loss.
Frequency Drift Analysis.
The tool extracts and aggregates all modal frequencies detected within the time interval analyzed, providing a frequency spectrum for the entire structure.
Dominant modal frequencies are automatically highlighted. Any shift in their value over time may suggest changes in stiffness, boundary conditions, or mass distribution.
