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.
