1 PRODUCT DATA Test for I-deas Core Software BZ-6000 Test for I-deas Core software provides foundation display, data management, and signal processing capabilities and is a prerequisite for most other Test for I-deas products. The software has many core features including an icon-driven user interface, programmability, hard-copy plotting, and the Test for I-deas Smart View online documentation. These common display and data management features enable test information to be more efficiently communicated and used throughout the engineering organisation. Core Components Three core components lay the foundation for the integrated measurement data acquisition, test data analysis, and Test-CAE integration functionality provided by Test for I-deas. These core components include: Base Test Test Geometry Time Data Processing

2 Base Test The Base Test module provides the framework and user interface for interactive, and batch software operation. Base Test provides an intuitive user interface, and delivers highly productive XY and XYZ graphing operations, extensive math operations, and advanced test data management capabilities. Fig. 1 The common Test for I-deas user interface, advanced graphics, and data management features provide core capabilities, enabling you to better understand and communicate test results User Interface A complete and customisable set of icons, menus, wizards and forms presents power and flexibility to the user in an intuitive framework. Both wizards and a logical, sequential arrangement of icons are used to guide new or occasional users through tasks. Experienced users will appreciate the utility of modifiable docking toolbars, and the ability to rearrange and create new toolbars using the supplied icons and their associated commands. Function Graphing A user interface provides highly productive XY and XYZ graphing operations for function data such as spectra, orders, time histories, and general XY pairs. The graphing facility provides extensive control of the display characteristics for both 2D and 3D function data in terms of formatting, colours, grids, and annotation. Specific icons provide a convenient way to access standard graph setups in addition to customised setups, which can be developed and stored for reuse. XY data records can also be retrieved and displayed by selecting the appropriate measurement location on a geometrical display of the test structure. A dynamic cursor aids in tagging, listing, calculating statistics, and interpreting graphed data. The spectra browser provides a highly interactive capability for presenting graphs in the form of narrow band, octave, 1/3 octave, 1/n octave; applying A,B,C weightings; and cursor selecting specific 2D slices of data. XY, stacked XY, XYZ, waterfalls, spectrograms and Campbell diagrams are supported. 2

3 Fig. 2 A comprehensive set of different graphical display and geometrybased display types provide extensive flexibility in presenting test information XY Graphs Single XY, overlay, sequential, multiple Y-axis, and two function graphs are provided. A convenient set of grid option forms provide extensive control over graph axis types including linear, log, db; grid line and fill colors; Y-axis scaling for linear, log, db, ISO numbering, etc.; labels, legends, text size and orientation; and number formats. A convenient set of data option forms provides extensive control over line, plate, and bar formats; different line styles, symbols, and colours for multiple overlay graphs; data smoothing; and visual reduction for displaying a reduced number of data points. Complex data formats include modulus and phase; modulus; real part and phase; real part; imaginary part and phase; imaginary part; real, imaginary, and phase; real and imaginary; phase; Nyquist; and orbit. Windowing is provided via cursor or keying desired ranges. Multiple Stacked XY Graphs A user-defined number of separate XY graphs can be stacked in a single viewport. Often this display is used to compare multiple graphs using a common X-axis (although it is also possible to display different independent X-axes). The same features previously described in the XY graphs section above are also provided for the stacked XY graphs. Waterfall, Spectrogram and XYZ Graphs The features previously described for XY graphs are also provided for XYZ graphs, as well as the following additional features: 3D views controlled by setting a defined view position or by controlling, in real-time, from the workstation Firmware graphics acceleration Z-axis set to represent time, RPM, record number, or any other variable Specific text and label orientation options for 3D viewing XYZ graph formats including surface, line, plate, and bar formats Both left- and right-hand coordinate systems Cursors and annotations: A real-time cursor provides continuous readouts of X, Y and Z values as the cursor traverses the data; tagging features enable you to tag and list the X and Y values of points of interest alongside the graph; and grid notes enable you to place general text annotations on the graph 3

4 Spectrograms and Campbell Diagrams Spectrograms and Campbell diagrams present data from rotating machinery tests in a special XY format, where frequency is graphed against RPM and the amplitude is represented by the colour gradients or size of symbols. Extensive options are included to provide easily interpreted displays covering the range of data complexity typically encountered in rotating machinery applications. Features include control of amplitude symbols in terms of circular or square, linear or log, colour, fill colour, maximum value scaling, and colour proportional to amplitude; a selectable range of orders; a range of optional order grid lines; and a selectable range of amplitude and order tolerances. Function Math Engine Extensive math operations provide flexible capabilities for customised processing of function data sets such as spectra, frequency response functions, orders, etc. Included are arithmetic operations and user-definable 2D or 3D colour bar chart displays. Editing functions include delete and replace with a constant, linear interpolation, or half cosine. A histogram task catalogues time history data into frequency distributions. The histogram shows the frequency of events in the data according to the predefined categories. Histogram counting techniques include data, time, peaks in range; level crossing, range amplitude count; rainflow, range pair, race track (ordered overall range) counting; and two-dimensional correlation. Function Creation Most function data results directly or indirectly from measurements. However, when it is necessary to create data, the following operations are valuable: Keyboard, digitising from a screen grid using a cursor or from paper using a tablet Algebraic expression evaluation Interpolation-linear or Lagrangian Reduction-constant bandwidth, octave, third octave, 1/n octave Decimation Project, File and Test Data Management All of the Test for I-deas applications contain new, efficient tools to improve lab productivity by addressing the need to make data conveniently accessible. Extensive, easy-to-use data management capabilities are provided for search and retrieval of data records from disk files. These capabilities are productive for use with small data files, as well as with large data sets, and multiple file environments. Multiple files can be searched to find the desired data using identifying attributes selected by the user. Data records may be selected for processing, display, or comparison in several ways: Use the data filter to automatically pass through data records from one or more files, satisfying any defined combination of the following criteria: disk record number, coordinate ID, version number, or function header attributes. User-defined attributes, or any Test for I-deas Data Manager attribute can also be used by activating a convenient switch Cursor-pick measurement points off a geometric display of the test structure or you use a selection form providing the following options: cursor-pick one or more records from a scrollable list of record names and other selectable attributes, specify a range of disk record numbers, specify a list containing a string of disk record numbers, or, specify a list containing a series of measurement coordinate identifiers 4

5 Fig. 3 Selecting attributes to append to the data Efficiency is enhanced by being able to group sets of functions as a single data management entity. Data integrity is assured by incorporating extensive identification information into an integral data file header and providing space for user-defined information. These data attributes can be set or modified on groups of functions. A central project file contains extensive data management information such as automatic units management, display format storage, processing setup conditions, and geometry management and display information. Even and uneven frequency or time point spacing are also supported. Open Architecture For those situations requiring some software development for process automation or integration with external software, we also deliver: Process Automation Recorder and Scripting: A complete framework for recording keystroke and button sequences is provided to capture and automate simple repetitive tasks. The captured sequences are stored in a text file and can be edited or extended with any text editor Data Import/Export: Enables function and geometry data exchange via several defacto industry standards such as Universal Files, spreadsheets, RPC, SDF and many others Fig. 4 Example of import function within Core Test ADF Library: This API and completely documented FORTRAN and C subroutine library supports read and write access to most of the Associated Data Files Test for I-deas Open Test API: Provides a framework for external software to be executed from within Test for I-deas software. This enables external software to do specialised calculations yet make use of the Test for I-deas graphics, Associated Data Files, programmability, and even, if desired, completely replace the user interface 5

6 Test Geometry The Test Geometry component augments the functionality of the Base Test component by adding the ability to seamlessly integrate and create test models, and enabling interaction with other geometry-based data from CAD, CAE and Test for I-deas modules. Fig. 5 Example of a geometry model Presenting data measured at many locations on the structure using a geometrybased display can provide a very efficient way of understanding and communicating test results. The extensive geometry creation and display capabilities of the Test for I-deas system are leveraged to provide convenient ways to view test data. Special features include easy-to-use methods for constructing geometry appropriate for testing applications. Geometry can be constructed using features such as: Creation of test measurement points (nodes) by keyboard entry and copy; reflect, interpolate; and cursor-picking measurement points from a detailed finite element model Global and local coordinate systems in Cartesian, cylindrical, or spherical systems. Local coordinate systems can be used to account for off-axis measurements Tracelines for wireframe displays Elements may be defined for advanced hidden line removed and shaded image displays and animations Groups of measurement points on different regions of the geometry can be defined to automate data processing/display A form- and icon-based user interface enables advanced geometry display technology to be easily applied to the display of test results on geometry. Results from modal analysis, order track tests, operating tests, or any other type of vector data at measurement points can be displayed as follows: Geometry displays: Deformed geometry display and animation for single or multiple viewports Line and shaded displays: Wireframe, hidden line removed, and shaded image deformation displays are available as static plots on all supported graphics hardware devices. Wireframe and hidden line removed animations are available on most supported devices, and shaded image animations are available on certain advanced graphics devices Arrow and criterion displays: Vector arrow displays enable viewing of acoustic intensity results Contour displays: Data such as acoustic pressures, acoustic intensities, or other general data can be displayed with color contours on geometry Transient animation: Displays of transient events defined from time histories can be animated on deformed geometry providing a clear understanding of the response measurement as a function of time Animation of order tracking measurements: Order track data from rotating machinery tests can be animated on geometry with the full range of animation features including wireframe, hidden line removed, and shaded image displays. The responses at a specified order and RPM or the total response can be animated 6

7 The Test Geometry component is not a prerequisite for Test for I-deas modal analysis modules, which focus on curve fitting and modal parameter extraction from measured data. However, it is required to visualise static and animated mode shapes, and to enter geometry for modal test, ODS and I-deas CAE correlation models. Time Data Processing The Time Data Processing component adds a specialised framework for performing rapid interactive or batch processing, editing and management of large time histories. A special lowoverhead family of 2D graphing routines streamlines the tasks of interactively identifying, cutting, pasting and editing sections of long recordings. Fig. 6 Example of a time history file The Time History task lets you manage and process time history records stored on disk. Time history records can be multichannel and unlimited in size with either even or uneven time point spacing. You can modify the sample rate of time history records, producing new records having the same time length but a different number of samples, through decimation or interpolation. Digital filtering includes FIR (Finite Impulse Response), low-pass, highpass, band-pass, band-reject, multiband filtering; sloped passband from integration and differentiation; rectangular, triangular, hamming, general hamming, hanning, Kaiser, Chebyshev mathematical windows; and resampling (interpolation, decimation). Peak valley reduction includes simple tolerance, range pair, and race track. Strip chart displays view large, multichannel time histories by zooming in, dividing into userdefined frames and then viewing on a frame-by-frame basis, or by moving to a specified frame location. Data frame(s) satisfying defined criteria can be automatically searched and displayed and editing is performed by convenient, interactive, cursor-driven features, including synchronised or nonsynchronised multichannel editing operations and concatenation of separate multichannel files. Frame statistics assist in automatically locating specific data occurrences in large time history files. Statistics are calculated per frame per channel. Time History Math Operations A subset of the math operations identified in the Function Math Engine of the Base Test component, which are appropriate for time history processing, are included for operating directly on large time history files, for example, offsets, scaling of a single record; and addition, subtraction, multiplication, and division of two records. 7
