Recording duration: 60 Minutes

Anyone dealing with installed machinery, or even test running motors in the service center, will encounter instances where structural resonance is amplifying machine vibration. The machine may meet stringent specifications in one instance but exceed acceptable vibration levels in another. A good understanding of natural frequencies and the tests necessary to identify them will help solve these vexing situations.

This presentation covers:

  • What is a natural frequency and why do they exist
  • How to conduct a basic bump test with a single channel analyzer
  • What is a modal analysis and what additional information does it provide
  • Related tests and concerns

This webinar is useful for service center technicians, supervisors and managers.
