nCode VibeSys: Vibration, Frequency, and Acoustic Analysis

Learn how to analyze measured vibration and acoustics data with nCode VibeSys

Required prequisite / foundational course - nCode GlyphWorks: Signal Processing and Test Data Analysis

Course overview - 1 day

nCode VibeSys: Vibration, Frequency, and Acoustic Analysis provides an overview of data analysis techniques and offers hands-on sessions where you will learn how to use nCode VibeSys software to quickly and efficiently turn measured vibration and acoustics data into actionable information.

Learning objectives

  • Display and interpret acoustic and vibration data in the time, frequency, revolution and waterfall and order domains
  • Identify modal parameters from measured data
  • Understand analysis techniques including signal processing, spectral analysis and order tracking
  • Animate wireframes and finite element models with measured vibration data
  • Compare and correlate mode shapes and frequencies with analytical results from finite element modeling
  • Obtain metrics for acoustic quality
  • Obtain metrics for human exposure to whole-body vibrations per ISO-2631, -5349, and others.

Topics included

  • Introduction to acoustics and vibration
  • Human perception
  • Analysis of rotating machinery
  • Structural dynamics and modal analysis

  • The frequency response function (FRF)
  • Experimental modal analysis (EMA)
  • Operating deflection shapes (ODS)
  • Correlation between EMA and FEA modal analysis
Who should attend

The nCode VibeSys: Vibration, Frequency, and Acoustic Analysis course is aimed at NVH, acoustics and dynamics engineers who need to analyze measured vibration data. This data is typically channels like acceleration, sound pressure, etc. from the field, proving ground or laboratory. It is assumed that attendees are familiar with data measurement practices and general signal processing concepts.
