Natural frequencies and mode shapes are often the key to understanding the dynamic characteristics of a machine or structure. Modal analysis can be applied by using a measured and controlled input force while simultaneously measuring structural response across a number of locations, providing direct transfer function information. Often the response due to normal operating conditions can be used to identify natural frequencies and modes shapes.

EDC has conducted modal analysis on a large number of machines and structures including:

  • Vibrating Screens
  • Crushers
  • Mills
  • Vehicles
  • Ships
  • Shiploaders
  • Balance Machines
  • Mining and offshore structures (TLO, Screen houses, wharfs etc)
