Fundamentals of Random Vibration and Shock Testing


This course will review basic vibrations, sources and causes and explore vibration measurements, analysis and calibration. Discussion is supported by projected visuals and video clips. Comparisons will be made between sinusoidal vs. random vibration with emphasis on testing systems, specifications, standards and procedures. ESS, HALT and HASS will be discussed and emphasis will be placed on vibration and shock test fixture design, fabrication, experimental evaluation and usage. Also shock measurement, shock response spectrum (SRS) and classical shock testing. Modal testing will be reviewed. Throughout, we emphasize topics you will use immediately.

Hands On Learning

This class will include time in the NTS Plano dynamic laboratory where attendees will view, hear and touch (hearing and feeling the differences between sine and random vibration) on shakers. We will perform a resonance demonstration, using first sine and then random vibration. We will demonstrate shock testing, using both a shaker and a shock test machine.

After this short course, you will be able to

  • measure vibration and shock,
  • calibrate vibration and shock measurement systems,
  • convert field measured data into a test program,
  • interpret vibration and shock test requirements,
  • supervise vibration and shock tests,
  • specify and experimentally evaluate vibration and shock test fixtures,
  • perform ESS, HALT and HASS.

When you visit a lab or review a test program, you will have a good understanding of the requirements and execution of dynamics tests and will be able to ask meaningful questions and understand lab technicians and test engineers responses.
