Vibration Training

271-01 Vibration Introduction

When you complete this lesson, you will be able to define basic terms and measurement units associated with vibration. You will also be able to describe the relationship between a machine’s operating speed and vibration problems.

  • 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’s rotational speed expressed in revolutions per minute (rpm) and cycles per minute (cpm)
  • Explain the relationship between machine rpm and orders

271-02 Vibration Causes and Characteristics

When you complete this lesson, you will be able to describe the characteristics of common, vibration-causing mechanical faults.

  • Discuss the common characteristics of a machine vibrating due to misalignment
  • Identify the signs of an unbalanced machine
  • Recognize the characteristics of vibration caused by:
    • Mechanical looseness
    • A faulty bearing
    • A faulty gear or belt
    • An electrical fault
  • Recognize the vibration characteristics exhibited by a machine experiencing oil whirl

271-04 Plant Vibration Program

When you complete this lesson, you will be able to describe a typical plant’s vibration program and discuss how it contributes to the plant’s operational readiness.

  • Describe the components of a typical vibration database
  • Explain why some equipment has permanently installed vibration equipment and describe how that equipment works
  • Describe how periodic vibration data collection with portable equipment fits into a plant’s vibration program
  • Identify the difference between vibration warnings and alarms, and discuss appropriate responses
  • Identify groups typically involved in a plant vibration program and describe their roles
