nCode VibeSys

Powerful System for Acoustics and Vibration Analysis

nCode VibeSys is a powerful data processing system for acoustics and vibration test data analysis. It is an easy-to-use software that enables acoustics and vibration engineers to design a reliable product that satisfies customers' expectations in terms of sound, comfort, and regulatory requirements.

VibeSys Structural Dynamics provides a range of noise and vibration analysis capability to compute the frequency response function of a structure and to assess its dynamic properties. 

VibeSys Human Perception provides a range of noise and vibration analysis capability to assess vehicle ride quality analysis to ISO 2631 standard and hand-arm vibration assessment to ISO 5349 standard, octave analysis, and psychoacoustic analysis.

VibeSys Rotating Machinery provides a range of analysis capability for detecting early symptoms of noise or vibration problems in rotating machinery, and identifying their root cause.

Product Options

Modal Analysis

Modal Analysis is a specialized product option for characterizing the dynamics of a machine or structure in terms of its dynamic properties. Modal analysis can easily be performed to answer questions such as: What are the modal frequencies? What are the damping ratios? What is the mode shape at a specific frequency? How good is a modal FE simulation compared to a modal test?

Accelerated Testing

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 Accelerated Testing, 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.

  • 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

Accelerated Testing is the only known supported commercial software that makes it possible to quantify the fatigue damage of a vibration test.

Introduction to Accelerated Testing in nCode GlyphWorks

GlyphBuilder

GlyphBuilder combines both Scripting glyph and Open glyph 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). With GlyphBuilder, users have the power to literally write their own glyphs!

Within the Scripting glyph, users can define their own processes by using MATLAB or Python programming language. IMSL math and statistic functions can also be accessed by using the special Python-enabled PyIMSL™ functions. 

Open Glyph directly enables external applications to be accessed from within a GlyphWorks process. The Open Glyph executes a given command line operation and in this way external code or scripts such as Visual Basic, Java, nCL, C++ etc., can all be called using data from the GlyphWorks process.

Media Display

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.

Data Cleaning

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 KalmanFilter glyph which accounts for noise in measured data using a physics model that predicts, given the current point, where the next point will be.
