Vibration Analysis


Using Vibration Analysis for Predictive Maintenance Services

Machinery vibration analysis is not magic:

Vibration analysis technology was developed for military purposes in the early 1950s. Over the past 20 years, industries have integrated this technology into existing maintenance programs. Think of vibration analysis as an EKG for your equipment. Vibration analysis allows you to look inside your machines nonintrusively during normal operation, saving costly downtime. Vibration analysis is useful in detecting specific faults early and monitoring the condition of the machine over time. This and other technologies allow maintenance departments to use their maintenance dollars more efficiently.

Today’s vibration analyzers can rapidly collect huge amounts of data. Good Vibrations can turn that data into useful information which will help you to prioritize your machine repairs. Good Vibrations collects data accurately and efficiently. We can provide on-site machinery vibration analysis to troubleshoot your problem equipment as well as long-term trending of data in a route‑based format.

In this picture, you can see the spalling that occurred in the bearing’s outer race; this defect was discovered using vibration analysis and trended for 3 months before the replacement was scheduled. This allows you to repair your equipment on your schedule, not the machine's schedule. We use the latest data analyzers to troubleshoot high, low and variable speed machines.


Types of faults identifiable using vibration analysis:

  • Imbalance
  • Belt Misalignment
  • Coupling Misalignment
  • Looseness
  • Resonance
  • Bent Shafts
  • Cocked Bearings
  • Lubrication Faults
  • Flow Turbulence
  • Worn Impeller
  • Electrical Defects
  • Anti-friction Bearing Faults
  • Inner Race
  • Outer Race
  • Ball/Roller
  • Cage
  • Cracked & Broken Gear Teeth
  • More.......

Good Vibrations can offer a complete turnkey vibration analysis program for your facility. This could include database creation, data collection, analysis, and a report generated in your choice of formats.

Remote Vibration Analysis

Today’s business climate doesn’t always allow having all the technical resources on site you would like. Remote vibration analysis uses your plant personnel to capture vibration data on your operating equipment based on your production schedules. Vibration data is then uploaded at a predefined time interval to the cloud for remote analysis. An ISO-certified CAT III Analyst performs the analysis and a written report is returned.

Good Vibrations recommends its customers use the GTi Predictive iPad-based data collection system due to its ease of use and the operator-friendly interface. Plant personnel will get a general idea of the equipment’s condition during the data collection, based on Red or Yellow alarm levels triggered on predefined ISO standards. Additional remote vibration analysis can be performed almost in real time on machines that have been returned to service or suddenly developed a problem using this system.

Remote analysis can be performed as a new complete turnkey system, including database creation and on-site training, to the analysis of your existing data due to personnel changes. We have been running successful programs from Texas to Canada since 2012. Emerson’s Machinery Health Manager Databases can also be used.
