The Modal analysis and Operating Deflection Shape (ODS) analysis module from OROS is a comprehensive software solution for structural dynamics, designed to determine how physical structures behave under dynamic loading. It combines ODS analysis, which visualizes actual deflection patterns during operation, with modal analysis, which identifies the inherent dynamic properties (such as natural frequencies, damping, and mode shapes) of a structure. The software is suitable for both novice and expert users, offering a user-friendly interface, advanced algorithms, and automated procedures for efficient test setup, data acquisition, and analysis. It includes a geometry builder for creating or importing structural models, supports various excitation methods (impact hammer, shakers, or operational), and provides direct integration with OROS analyzers for field and laboratory use. The solution is widely used for validating simulation results, optimizing mechanical designs, and supporting maintenance decisions in industrial, automotive, aerospace, and research applications.
