Enter, edit, and view vibration specification data


The Vibration Manager is a database that contains over 100 vibration entries, including UK DEF STAN 00-35 Part 3 Issue 4 Chapter 2-01 Annex A; USA MIL-STD-810G Method 514.6 Vibration Annex C; Civil Aircraft Standard RTCA DO-160G; the Electric Vehicle Battery Test Procedures Manual, Revision 2, Published January 1996; and ISO 16750-3:2012 describing the mechanical loads for electrical and electronic equipment in road vehicles. It enables graphical comparison of up to 16 overlaid vibration curves, data import/export capabilities via XML files, and contains filters to find curves of interest within database.

Identify modes of vibration and extract modal parameters   

 

Modal Analysis is a specialized product option that identifies modes of vibration and extract modal parameters. It can also animate mode shapes or display Operating Deflection Shapes (ODS) with color-filled contours during animation. 

 

Modal Analysis features: 

  • More accurate damping ratios through enhanced FE modelling 
  • Modal Assurance Criterion (MAC) analysis to determine the similarity of mode shapes by comparing the response motion captured using virtual sensors with the measured displacements
  • "AutoMAC" matrix to help position virtual sensors and optimize physical instrumentation to capture the modes of interest
  • Rapidly comparison of different designs in terms of their dynamic properties
  • Noise and vibration related troubleshooting
  • Structural Health Monitoring by tracking changes in modal parameters due to damage

Vibration test profile design

 

Vibration Profile Design (formerly Accelerated Testing) provides the ability to create a representative PSD or swept sine shaker vibration test based on measured data. It uses the fatigue damage spectrum approach as described in NATO STANAG 4370 (AECTP-240)/ UK DefStan 00-35/Mil-Std-810G, allowing users to tailor vibration tests to a target vibration environment. With Vibration Profile Design, users can also compare existing test evidence against the requirements of a known test specification, enabling assessment of whether components in service will likely survive to the target service life. This known safety margin may help extend the life of parts in service or conversely avoid unexpected failures.

With Vibration Profile Design you can:

  • Create an accelerated shaker test and assess the impact on shock and fatigue damage
  • Rapidly compare an existing test specification with service vibration data
  • Extend the life of parts in-service or avoid unexpected failures
  • Understand the impact of exposure time in-service and on the test rig

Display and synchronize video with data

 

Media Display glyph enables video and audio signals to be played using Windows Media® player embedded in the glyph. It also enables cursor synchronization with other data displays to gain insight on what was occurring in other signals. The Gauge Display glyph enables synchronized values to be displayed during playback in a variety of styles such as angular gauges or digital read-outs. The Video Player glyph can display multiple synchronized videos. It enables cursor synchronization with other data displays and multiple Video Players can run in synchronization.

Custom methods and file formats


GlyphBuilder combines both Scripting glyph and OpenGlyph capabilities, enabling users to add their own unique or proprietary methods and file formats to GlyphWorks. The Scripting glyph enables new functionality to be added to GlyphWorks by using MATLAB or Python programming language (can be downloaded at www.python.org). Both Python 2 and Python 3 are supported.

OpenGlyph directly enables external applications such as Visual Basic, Java, nCL, and C++ to be accessed from within a GlyphWorks process.

Advanced data cleaning and denoising

 

The Data Cleaning option provides advance data cleaning techniques beyond what is possible with classical filtering techniques alone. This option includes the Wavelet Denoising glyph that enables noise to be separated out from signals by decomposing data into the combination of “wavelet levels”. It also includes the Kalman Filter glyph which accounts for noise in measured data using a physics model that predicts, given the current point, where the next point will be.
