Introduction to ME’scopeVES
A brief introduction to the ME’scope Visual Engineering Series, including tools and advanced 3D model and shape animation capabilities.
Building and Animating a Plate Model
This video takes you through the three basic steps that are required for animating your shape data in ME’scopeVES: 1) build a geometric model of the test structure, 2) import your data into a Data Block file, and 3) assign measurements in the Data Block to points and directions on the model.
Drawing a 3D Structure Model
This video demonstrates several different ways for building 3D structure models in ME’scopeVES; 1) using the Drawing Assistant, 2) building a model using Points, Lines, and Surfaces, 3) Extruding a 2D SubStructure into a 3D model, and 4) tracing a 2D profile from a digital photgraph.
Displaying Shapes in Animation
This video includes more of the details of animating shapes on a structure model. It covers: 1) measurement coordinates, 2) animation equations, 3) interpolation, and 4) many of the commands in the Animate menu.
Basic Modal Analysis
This video is an introduction to modal parameter estimation, or curve fitting. It covers the basic steps of curve fitting; 1) count the modes on a mode indicator graph, 2) estimate modal frequency and damping, 3) estimate modal residues, and 4) save the modal parameters into a Shape Table.
Operational Modal Analysis
This video illustrates the curve fitting capabilities of the Operational Modal Analysis Option in ME’scopeVES. To simulate an OMA, a “round trip” is performed using a modal model. The MIMO Simulator in the Acquisition window is used to “excite” the modal model of the structure with a random force. Acceleration Cross spectra are then “acquired” and curve fit to recover the modes of the modal model.
This tutorial illustrates the capabilities of the Experimental FEA Option in ME’scopeVES. A finite element model is constructed from a PhotoModel on a beam structure. The finite element model is then solved for its analytical modes, and they are compared with the experimental modes of the actual structure.
FEA Model Updating
This tutorial illustrates the capabilities of the FEA Model Updating Option in ME’scopeVES. The FEA model constructed in the Experimental FEA tutorial is used for model updated. The thickness of the vertical plate in the model is updated so that its analytical modes more closely match the experimental modes of the structure.
Advanced Techniques for Drawing Models
This video illustrates the use of some of the advanced drawing capabilities in ME’scopeVES for creating 3D models. In it you will learn how to 1) download a model from the Vibrant Internet model store, 2) create part profiles from machine drawings, and 3) create 3D machine parts from 2D profiles.
Impact Testing for Modal Analysis
Using a Dytran (www.dytran.com) impact hammer and tri-axial accelerometer, the modes of a simple I-beam are determined and animated using Vibrant Technology’s ME’scopeVES (www.vibetech.com).
