What is MEscope Visual ODS?
An animated ODS shows how your machine or structure is moving in slow motion. When animating the ODSs of a structure, you can see what cannot be seen otherwise; the general movement of one structure and the movement of one part in relation to another. Excessive vibration levels and loose or damaged parts are easily identified on an animated ODS display.
Visual ODS lets you see how a machine or structure is moving by animating ODSs directly from an experimental dataset in the frequency domain.
Example of using Visual ODS
A fan located on the roof of a building was experiencing strong vibrations, loosening belts and creating high levels of noise and vibration throughout the building. All attempts to balance the fan did not solve the problem.
An ODS data set was obtained while the fan was running, using a 2-channel analyzer with a tachometer signal. A Peak and Phase data set at engine operating speed was acquired. The animated ODS showed that the motor base at the opposite end of the belt was moving out of phase with the engine. Removing some paint from the engine base revealed a previously undetected crack in the engine holder. After repairing the crack, the fan was rebalanced and the serious problem of vibration and noise was resolved.
Visual ODS Features
Interactive 3D structure model
- Create 3D structure models to display Animated ODSs, using points, lines, surface triangles, and surface quadrants
- No limits to model size
- Each point in the 3D model has its own local measuring axes (in rectangular, cylindrical, spherical, or machine coordinates). The measuring axes are plotted at each point to match the sensor measurement directions
- The animated display of all unmeasured points and directions is interpolated from the animated motion of near measured points and directions
- Light sources are used to make solid models look more realistic
- Photo-realistic models (3D models made of digital photos) provide more realistic animations
- Transparent surfaces allow better clarity of the movement of hidden parts of the structure
- The contours of the 2D structure model can be traced from photographs or digital drawings.
- 2D models can be extruded or revolving to create 3D models
- On screen, scaling, shape, positioning, and rotation of all drawing objects
- Create substructures of selected points, lines, and surfaces to break complex models into components with simpler geometries. Substructures can also be moved, hidden, and made transparent for clarity
- Drawing assistant. Quickly create 3D models using a library of editable, user-built substructures
- The 3D model can be displayed in quadruple view (X, Y, and Z and interactive 3D user view) or in a single view
- Zoom, pan, rotate, and change the perspective distance of the model
- Cut, copy, and paste drawing objects
- Copy and paste properties into the drawing object worksheet
- The speed of the rotational substructures is synchronized with the speed of the SDDs tracked in order
- Imports structure templates from more than 14 different third-party disk files
Time and frequency domain measurements
- Imported data from the most popular analyzers, recorders, data acquisition systems, and portable data collectors
- All popular types of time and frequency domain measurements can be imported
- No limits on the number of measurements or the number of samples per measurement
- Measurements can be displayed in Real, Imaginary, Magnitude (Linear, Log, dB), Phase, CoQuad (Real and Imaginary), Goat (Magnitude and Phase), Nyquist, and Orbit charts
- Measurements can be displayed in row/column, chart, waterfall, overlaid, or overlaid by DOF and color map formats
- The measurement display can be enlarged and scrolled
- Line, peak, and band cursors can be displayed on each measurement
- All graphics can be copied to the clipboard as bitmap or metafile
- All sheet properties can be copied and pasted using the Windows clipboard
- Imports peak and phase data for order-based SOD animation
- Imports measurement data from more than 40 different third-party disk files
Animated display of ODS's and mode shapes
- Interactive scanning, pause, or static display of ODSs directly from time or frequency measurements, using the line, peak, or band cursor
- Interactive scan, permanence, or static display of modal shapes or ODSs of a shape table
- Interpolation of shapes. Geometrically weighted calculation of shape values for unmeasured DOFs using data from nearby measured DOFs
- ODS comparison view of two data blocks or shape tables in side-by-side or overlaid format
- Animated shape display using Deformation, Arrows, Text Values, or Surface Contour Colors with Node Lines
- Animation with persistence to display orbit data at each point.
- Hidden line and transparent surface display for clarity
- Digital movies (Windows WMFs) can be created during shape animation. Recorded animations can be incorporated into MS Power Point presentations.
- Mode and ODS formats can be imported from more than 10 different third-party disk files
Scripts with hotkeys
- Scripts make it easy to perform repetitive tasks and a sequence of commands for demonstration purposes.
- A script is a spreadsheet of names and commands from the ME'scope window. Each line of a macro-program contains an ME'scope data file window and a command to run in that window
- When a macro-program runs, all commands in the macro run in sequence from top to bottom
- Hotkeys. Any script can be executed by pressing your hotkey in the ME'scope menu bar
