Model updating using operational data Free chatrooms for iphones
Its industry-leading interactive 3D animation allows you to observe order-related operating deflection shapes from running machinery, resonant vibration and mode shapes from real structures, acoustic shapes, and engineering shapes directly from acquired data.
In addition to its photo-realistic interactive animated display, ME’scope VES contains state of the art tools for performing: • FRF-Based Modal Analysis • Operational Modal Analysis • Vibro-Acoustic Analysis • Dynamics Modeling & Simulation • Structural Dynamics Modification • FEA Model Updating An Operating Deflection Shape (ODS) is the simplest way to see how a machine or structure moves during its operation, either at a specific frequency or moment in time.
With this animation, you can observe resonant vibration as well as order-related and other types of forced vibration.
Modal analysis is used to characterize resonant vibration in mechanical structures.
At the heart of the Basic Modal Analysis option is the ME’scope Polynomial method, an easy to use MDOF curve fitter.
This curve fitter can be used to simultaneously extract parameters for multiple modes, especially in cases of high modal density.
You can stop the animation, back it up, and play it forward to observe in slow-motion phenomena that may have taken place very quickly in real time.
With frequency-based ODS animation, you simply move the cursor to a frequency of interest in your data, and the ODS for that frequency is displayed.
With ME’scope, you can import or directly acquire multi-channel time or frequency data from a machine or structure, and post-process it.It can also extract local modes where the resonant vibration is confined to a local region of the structure.Each resonance has a specific “natural” or modal frequency, a modal damping or decay value, and a mode shape.FRF-Based parameter estimation (or curve fitting) is used to estimate the modal parameters of a structure from a set of FRFs.
An ODS contains the overall dynamic response of a structure due to forced and resonant vibration.Time-based ODS animation sweeps a cursor through a set of time histories describing motions at multiple points and directions on a test article.
