Structural dynamics is a type of structural analysis which finds out the behavior of a physical structure when it is subjected to dynamic loading. It includes Operating Deflection Shape (ODS) analysis and modal analysis, which shows the actual deflection patterns under certain operating conditions and identifies the inherent dynamic properties of a structure, respectively. Modal testing solution is a comprehensive package for modal experts as well as novice engineers. OROS Modal analysis is an application-oriented software associating the latest algorithms with a user-friendly interface and automatic procedures for Operating Deflection Shape (ODS) and modal parameter identification. The software contains several functions to create a geometry in order to match any machines. Predefined standard elements (circle, cube, cylinder …) are available as well as a dedicated interface to create a geometry manually. The local coordinates systems (Cartesian, cylindrical, spherical) allow to define the correct directions on each measurement points. A geometry can also be imported from others software (experimental and simulation software). Data acquisition is a critical step for modal analysis: without correct data, no exploitable results. Thanks to the direct acquisition implemented in Modal, enjoy the Teamwork analyzers power and accuracy with a dedicated interface for structural acquisition. The interface works with the different excitation modes: impact hammer, shaker, operating excitation. To excite a large structure, up to 6 shakers per analyzers can receive signals from generators outputs. In order to fit the wide range of potential cases
