The OROS Modal Analysis module is a comprehensive software solution for structural dynamics, designed to determine the modal parameters—such as natural frequencies, damping ratios, and mode shapes—of engineering structures. It supports both Experimental Modal Analysis (EMA) and Operational Modal Analysis (OMA), enabling users to analyze how structures respond to dynamic excitation. The software features an interactive geometry builder for creating and editing structural models, supports direct data acquisition from OROS analyzers, and offers advanced signal processing tools for accurate modal identification. It is suitable for both laboratory and field environments, providing a user-friendly interface, automated procedures, and compatibility with various data formats (including UFF and IGES). The solution is widely used for validating simulation results, optimizing mechanical designs, and supporting maintenance and diagnostics in industries such as manufacturing, construction, and transportation.
