Vibration, Frequency, and Acoustic Analysis

Learn how to analyze measured vibration and acoustics data

Course overview - 1 day

In this course, you will learn how to quickly and efficiently turn measured vibration and acoustics measurements into actionable information using nCode VibeSys software.

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

Who should attend

The 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. Attendance of Digital Signal Processing and Test Data Analysis training course is a prerequisite for this course.
