Modal & Operating Deflection Shape (ODS) Analysis - With Solutions!

Modal testing and analysis of the data provides a 3D model of the machine or structure being tested. Modal testing helps identify natural frequencies, mode shapes and damping associated with each natural frequency measured. Modal testing is conducted with the machine in a static mode (not-operating).

 

Operating Deflection Shape (ODS) measures and displays how a machine or structure responds as it operates. The 3D animated (ODS) models show how the machine responds to forces at the frequencies caused by different machine problems or conditions.

 

The following are a few examples:

  • Unbalance
  • Misalignment
  • Weak support base, soft foot or loose anchor bolts
  • Eccentricity
  • Resonance response in machines, bases, structures or piping
  • Excessive flexing (Suggesting Resonance)
