Vibration Introduction

Learning objectives

  • Explain the relationship between excitation and vibration
  • Describe the time and frequency domains of vibration measurement
  • Describe the three basic measurements for vibration amplitude:
    • Displacement
    • Velocity
    • Acceleration
  • Identify the mathematical relationship between those three attributes and give reasons for measuring each
  • Describe the relationship between a machine‚Äôs rotational speed expressed in revolutions per minute (rpm) and cycles per minute (cpm)
  • Explain the relationship between machine rpm and orders

Course overview

Many parameters are measured for information about systems and components. But, vibration is the best parameter for measuring operating equipment. Vibration helps you understand when equipment is not operating correctly. It can also help diagnose and troubleshoot problems. The Vibration Introduction course defines basic terms and measurement units for vibration. It also describes the relationship between a machine's operating speed and vibration problems.

This online course explains vibration and excitation. It reviews amplitude units, including displacement, velocity, and acceleration, and their mathematical relationships. It details time and frequency domains and covers revolutions, cycles, and orders. Vibration Introduction is part of the Vibration training series.
