Digital Signal Processing and Test Data Analysis

Course Overview

This course will show you how to use nCode GlyphWorks software to quickly and efficiently turn raw data into actionable information. Class time is split between lecture on data analysis techniques and hands-on sessions where you get to put concepts into action with GlyphWorks software.

Course Objectives

  • Analyzing data with pre-designed engineering functions called ‘glyphs’
  • Solving engineering problems
  • Displaying and interpreting results

Analysis techniques include signal processing, statistical analysis, vibration analysis, and durability assessment.

Course Concepts

  • Displaying by time series, histogram, charts and reports, synchronizing measured signals with GPS and video
  • Identifying and correcting errors and problems with measured data
  • Identifying and analyzing channels of interest.
  • Identifying and extracting key sections of measured signals
  • Performing math operations on single, multiple and combined channels
  • Classifying data into rainflow cycle counts, FFT-PSD and other statistical measures
  • Durability analysis, including strain gauge rosette processing, fatigue analysis and crack growth
  • Creating frequently used mini-processes with a SuperGylph
  • Customizing your own glyph from scratch using Python or Matlab
  • Importing data from and exporting to 3rd party formats

Course Agenda

Duration: 2 Days

Day 1

  • Learning the nCode interface
  • Importing and exporting data
  • Graphically displaying data
  • Manipulating and analyzing data
  • Cleaning and editing bad or anomalous data
  • Tips and tricks

Day 2

  • Using metadata in automated calculations
  • Automated report generation
  • Advanced analysis techniques:
    • Fatigue analysis and fatigue editing
    • Frequency
    • Crack growth
    • Optimized proving ground testing
    • Analysis of rotating machinery
    • GlyphBuilder

Course Timing

This class covers 2 days’ time according to the agenda outlined above. The mix of subject matter can be adjusted to suit the attendees. The schedule for day 1 is fixed – because it covers the basics that all users will need. The timing of day 2 can be adjusted to maximize the time spent on topics that matter the most to the students

Who Should Attend?

The course is aimed at engineers who need to analyze measured test data. This data is typically channels like strain, acceleration, load, temperature, etc. from the field, proving ground, or laboratory.

It is assumed that attendees are familiar with data measurement practices and general signal processing concepts. No prior knowledge of nCode software is required.

Upcoming Classes

Please note that classes organized outside of North America are subject to VAT. VAT will depend on the office that organizes the event or where it is held, regardless of where the attendee resides.
