The ME’scopeVES Visual Engineering Series of software packages and options makes it easier for you to observe and analyze noise & vibration problems in machinery and structures using either experimental or analytical data.   With ME’scope, you can import or directly acquire multi-channel time or frequency data from a machine or structure, and post-process it. 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’scopeVES 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.  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.  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 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.  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.   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.  It can also extract local modes where the resonant vibration is confined to a local region of the structure.   The Multi-Reference Modal Analysis option contains all of the features of the Basic Modal Analysis option, plus additional methods for curve fitting a multiple reference set of FRFs. Multi- Reference curve fitting is used to extract closely coupled modes and repeated roots (two or more modes at the same frequency).  This option contains a Stability diagram for locating stable pole estimates, and three additional curve fitting methods: Complex Exponential, Z-Polynomial, and the patented AF Polynomial method.
