ARMS Reliability is now a part of Bently Nevada. This is a Bently Nevada run course.

Learning Objectives

  • Explain how the fundamentals of machine design and behavior are reflected in the vibration measurements.
  • Reduce machine vibration data into usable plot formats. Explain which plot formats are best to use in the different stages of machine diagnostics.
  • Describe the causes, effects, and indicators of the typical machine malfunctions; including recognition of problems such as unbalance, misalignment, rubs, shaft cracks, and fluid-induced instabilities.
