15 Introduction To enlarge this text, click on it, hold down the Ctrl key and spin the mouse wheel. ME scope is a series of software packages and options that makes it easier for you to acquire, analyze, observe and document noise & vibration in mechanical structures and operating machinery. You can use ME'scope to care out a wide variety of engineering tasks. Vibration & Acoustic Data Acquisition Vibration & Acoustic Signal Processing Operating Deflection Shape (ODS) Analysis Experimental Modal Analysis (EMA) Operational Modal Analysis (OMA) Vibro-Acoustic Analysis Multi-Input Multi-Output (MIMO) Modeling & Simulation Structural Dynamics Modification (SDM) Finite Element Analysis (FEA) FEA Model Updating ME'scope can also be used as the "heart" of an acquisition & post-processing system for remotely monitoring, analyzing, and diagnosing failures in operating machinery or in structures such as bridges and wind turbines. When used together with its archival database and operator Console graphics software, ME'scope can be used for, Machinery Health Monitoring (MHM) Structural Health Monitoring (SHM) Environmental Monitoring Qualification Testing Animated Shape Display Animation of a Photo Realistic Model. 15

16 Types of Measurements Imported All ME'scope packages contain a state-of-the-art interactive animated display of spatially defined shapes on a 3D model of a machine or structure. Shape data such as an operating deflection shape (ODS), mode shape, acoustic intensity shape, or sound power through a surface can be displayed in animation on a photo realistic model, like the one shown above. Displaying shapes in animation makes it easier to visualize and analyze structural noise & vibration problems. Observing Vibration in Slow Motion By animating the spatial response of a structure in slow motion, you can view overall motion of a structure, and the motion of one portion relative to another. Locations of excessive vibration or high noise levels are easily identified. With interactive sweep animation, you can sweep through a set of time histories and observe the recorded response of a structure, whether it is sinusoidal, random, transient, linear or non-linear, stationary or non-stationary. With interactive dwell animation, you can dwell at a specific time or frequency in a set of responses, and display shapes using either sine dwell or stationary dwell. Types of Measurements Imported Every ME scope package can import multi-channel data from a wide variety of third party data files. File formats used by all popular multi-channel data acquisition systems, analyzers, recorders, and data collectors are supported. Over 45 different file formats are supported, including ASCII text spreadsheet, MATLAB, DADiSP, Microsoft WAV, and Universal File Format (UFF). ME'scope can import most of the popular kinds of time or frequency domain measurement functions. The following types of measurement functions are recognized by ME'scope. Time Domain Functions Time Waveform (vibration, sound pressure, strain gauge, temperature, etc.) Auto Correlation Cross Correlation Impulse Response Function (IRF) Frequency Domain Functions Fourier Spectrum (FFT of a sampled Time Waveform) Auto Spectrum Cross Spectrum Power Spectral Density (PSD) Frequency Response Function (FRF) (Response / Force) Transfer Function (Output / Input) Transmissibility (Roving response / Reference response) Coherence (Ordinary, Multiple & Partial) ODS FRF (Roving response Auto Spectrum & phase relative to a Reference response) Acoustic Intensity Sound Pressure Level 16

17 Time-Based ODS Animation With ME'scope, you can animate time-based Operating Deflection Shapes (ODS's) directly from multi-channel data that was acquired spatially from a machine or structure. Time-domain Sweep Animation is done by sweeping a cursor through a set of time histories. You can stop the animation, back it up, and play it forward to observe in slow motion vibration phenomena that may have taken place very quickly in real time. For example, you can observe in slow motion the run up, coast down, or other transient behavior of a machine. During this transition period, the machine may pass through a variety of vibrational states, due to resonances, unbalances, varying loads, fluid flow, etc. Frequency-Based ODS Animation Sweep Animation from Multi-Channel Time Responses. With ME'scope, you can animate frequency-based ODS's (Operating Deflection Shapes) directly from data that was acquired from a machine or structure During Sine Dwell animation, the ODS at a specific frequency is displayed using sinusoidal modulation. A frequency-based ODS allows you to see how a structure behaves at a single frequency. While dwelling at a frequency, the ODS will show you where vibration levels are highest, and will indicate loose parts and connections. A frequency-based ODS can also help you determine whether or not a resonance is being excited, or whether the vibration is an order related forced vibration. Sine Dwell Animation of an ODS Near a Resonance. 17

18 Mode Shape Animation Mode Shape Animation Modes of vibration are used to characterize resonant vibration in machinery and structures. All structures have specific natural frequencies at which they readily absorb energy When a resonance is excited, it can cause excessive noise and vibration, resulting in premature structural failures Each resonance, or mode of vibration, is defined by its natural frequency, damping, and mode shape At or near a modal frequency, the response of a structure is usually dominated by the resonance A frequency-based ODS will often look like the mode shape of a nearby resonance, if the resonant response dominates the ODS However, mode shapes, along with their frequency and damping values, are more accurately obtained by curve fitting a set of FRF measurements, or a set of Fourier spectra, Cross spectra or ODS FRFs calculated from operating data. Documentation with Videos Sine Dwell Animation of a Mode Shape. ME'scope allows you to interactively record a video of any shape animation. A video is a sequence of animation frames saved into a Microsoft Windows WMV file Videos can be played back on any computer that can play WMV files You can send videos to your clients, and they can view the animation just as it appears in ME'scope. Videos can also be embedded in Microsoft Power Point presentations or Word documents, and played by clicking on them. Individual frames can be cut from a video and pasted into documents, or annotations added to frames with a graphics or text processor. Projects, Data Files, and Windows Dialog open while recording a video 18

19 All work in ME'scope is done in the currently open Project file. Only one Project file can be open at a time in ME'scope. A Project file (with file name extension.vtprj) can contain one (or more) of the following data files, Structure (STR) file Data Block (BLK) file Shape Table (SHP) file Report (RTF) file Script (VSL) file Added files Acquisition (ACQ) file All of the data in these files is contained within the Project file on disk, (except Added files) Added files are stored separately on disk, and are opened in a separate application program when opened in ME'scope ME'scope Window The ME'scope window is always open when ME'scope is running Data File Windows ME'scope Window. A separate window is used to display and manipulate the contents of each data file within the currently open Project. When a data file is opened, a copy of its contents on disk is put into RAM memory and displayed in its own window. 19

20 Mouse Operations An STR file is displayed in Structure window. A BLK file is displayed in a Data Block window. An SHP file is displayed in a Shape Table window. An ACQ file is displayed in an Acquisition window. An RTF file is displayed in a Report window. A VSL file is displayed in a Script window. Saving Data Files ME'scope with a Structure (STR) and Data Block (BLK) Window Open. When a file is saved in ME'scope, its file contents in RAM memory replace the contents of the file in its (VTprj) file stored on disk. If a Project is closed without saving changes to one of its data files, the file contents in memory will be lost and the contents of that file on disk will not be changed.

29 Shape Table (SHP) Window Data Block Window Showing Four M#s in Row-Column Format. A Shape Table (SHP) file contains multiple shapes. Shapes can be displayed in animation directly from a Shape Table, on the structure model in a connected Structure window. A "shape" is defined as any data from two or more measurements made at different test points & directions on the machine, structure or acoustic surface. Common types of shapes are Operating Deflection Shapes (ODS's), mode shapes, acoustic shapes, and engineering data shapes. Each shape in a Shape Table has one or more shape components. Each shape component has a unique measurement number (M#). A Shape Table (SHP) file is used in a variety of different ways; 1. Save it from a Data Block window during animation or curve fitting. 2. Save it from an SDM, FEA, or FEA Model Updating calculation. 3. Save it from a Forced Sinusoidal Response calculation in a Data Block or Shape Table window. 4. Import it from a third party disk file. 5. Create a new Shape Table, and Manually enter data into it. Adding a Shape Table to a Project There are several ways to add a Shape Table to a Project; 1. Execute File Import Shape Table, and import shapes from a third party data file. 2. Double click on a Shape Table (SHP) file in the (right or lower) pane of the Project Fly-out Panel. 3. Right click on a Shape Table (SHP) file in the (right or lower) pane of the Project Fly-out Panel, and select Open from the menu. Creating a Shape Table There are several ways to create a new Shape Table in a Project; 1. Execute File New Shape Table in the ME'scope window, and manually enter or paste data into its Shape and DOFs spreadsheets. 29

31 Changing the Animation Speed The animation may be too fast or too slow, depending on the speed of your computer. To change the animation speed, 1. Click on the Structure window Title bar to make it active. 2. Hover the mouse pointer over the Structure window Toolbar to display the Tool tips. 3. Locate the Animate Speed Increase Speed (rabbit) and Animate Speed Decrease Speed (turtle) Tools on either side of the Animation Method Tools. 4. Click on the Turtle Tool to decrease the animation speed. Click on the Rabbit Tool to increase the speed. Quad View versus Single View Time-Based ODS Demo Showing Sweep Animation. The Structure window can display a single View of the structure model, or four Views together in a Quad View format. 1. 3D View (upper right quadrant). 2. Z Axis View (upper left quadrant). 3. X Axis View (lower left quadrant). 4. Y Axis View (lower right quadrant). When the Vertical Axis is changed on the Display tab in the File Structure Options box, the labeling of the three 2D Views will also change. To change between the Quad View and one of the four Views, Double click on the single View to display the Quad View. Double click on a single View in the Quad View to display that View. Active View When the Structure window is in Quad View, the active View is indicated by the yellow box in the Display View button. 31

32 Frequency-Based ODS Demo Zoom Pan Click on a View to make it active. When the 3D View is active the upper right quadrant of the Display View button is yellow. In Quad View, click on each View to make it the active View turns yellow on the Display View Tool. Click in a View to make it active, and spin the mouse wheel to Zoom the structure in that View. Hold down the Shift key and drag the mouse to Pan the structure model in the active View. Rotation in the 3D View Click & drag in the 3D View to rotate the structure. Interpolated Motion The deformation of the Antenna structure model is being created using data from only four Traces in the Data Block window. Without interpolation, these four points (the numbered points on the 3D model) would be the only ones moving during animation. Most of the points on the model are unmeasured points, but they are moving also. The motion of each unmeasured point is being interpolated from the motions of nearby measured points. Execute Animate With Interpolation several times in the Structure window to disable and enable geometric interpolation. Notice that with interpolation enabled, the cantilevered motion of the model is influenced by of the motions of the four Measured DOFs, plus the influence of Fixed DOFs at the base of the antenna. Frequency-Based ODS Demo 1. Hover the mouse pointer over the Demos tab to display the Demos fly out panel. 2. Make sure the Help Show Tool Tips is checked. 3. Move the mouse pointer over the Demos panel to display the Jim Beam.VTprj Project name, and double click to open the Project. 4. Execute Draw Animate Shapes in the Structure (STR) window. Sine Dwell animation using shape data from a Data Block will begin. Notice that the Line cursor (vertical red line) is positioned in the middle of the Data Block M#s. The 3D model is being animated with the ODS (data from each M#) at the cursor position. Sinusoidal modulation of the ODS is used to create the sine dwell animation. 5. To view each FRF measurement, drag the vertical scroll bar on the right side of the graphics area in the Data Block window. Animating Near a Resonance The peaks in the FRF measurements are evidence of structural resonances, or modes of vibration. At or near a resonance peak, the ODS (values of the FRFs) is being dominated by the mode shape associated with the resonance. For lightly damped structures, the ODS at or near a resonant frequency will closely approximate the mode shape. To view the ODS at a resonance, 1. Execute Format Overlaid to display all FRFs overlaid on one another. 2. Execute Display Imaginary to display the Imaginary parts of the FRFs in Overlaid format. 3. Click & Drag the Line cursor in the Data Block window until it lies on or near one of the resonance peaks. At one of the lower frequency resonance peaks, the ODS on the structure model should look like a bending or torsional mode shape of the structure. 32
