Vibration Analysis

O'Donnell Consulting - Vibration Analysis
Vibration analysis is performed not only to determine design life of structures, but also determine how a component may have failed. Most physical systems vibrate – inherent vibration modes in structures can shorten equipment life, and cause premature failure. Often, these failures are catastrophic.

When a physical system vibrates, it does so at particular natural frequencies – these frequencies and resulting mode shapes can be determined using Modal Analysis. Often, simple modal analysis can be performed, while for more complex systems, finite element analysis is performed to determine to determine the dynamic response.

We have performed vibration analyses on valves, medical equipment, electronic components, and structural support systems, among other components. We identify potential operating problems and prepare recommendations regarding system and operating procedure modifications. (If the deletion or addition of a support would chase a vibration problem to another location in the system, we would know it in advance of making the change).

  • Vibration Troubleshooting and Repair
  • Simple and Complex Modal Analysis
  • Flow Induced Vibrations
  • Rotating Equipment Analysis

We have performed:

  • Vibration and shock analysis of nuclear equipment in land-based and shipboard applications
  • Seismic analysis of tanks, vessels, skids and welded structures
  • Vibration analysis of equipment including compressors, shafts, piping, and money shredding machines

For a comprehensive list of structures that we have analyzed, see Components. For a summary of our various engineering projects, see Portfolio.
