Overview

OROS Modal is a high-performance software dedicated to structural dynamics. It allows engineers to identify the dynamic characteristics of structures through Modal Analysis (EMA/OMA) and Operating Deflection Shapes (ODS).

**Complete Workflow**: From geometry definition to parameter identification.
**Ease of Use**: Intuitive interface designed for experimentalists.
**Accuracy**: State-of-the-art algorithms for damping and frequency estimation.
**Integration**: Fully compatible with OROS noise and vibration analyzers.

Software Modules

Geometry Define your structure with nodes, lines, and surfaces.	Acquisition Setup channels, impact hammer, or shaker tests.	Processing Frequency Response Functions (FRF) and Coherence.
Identification Extract Modal Parameters: EMA, OMA, and ODS.	Validation MAC and COMAC for model validation and comparison.	Import / Export Universal file formats (UFF), Excel, and reporting.
