Who We Are

Founded by Ray W. Rhoe, P.E., Vibration Analysts, Inc. was created with more than 100 years of combined vibration analysis experience and knowledge.

Principles of Our Work

  • Provide all services in a professioinal and courteous manner.
  • Never issue an invoice for more than the quoted amount.
  • Provide all required test equipment. If we don’t have it, we’ll buy it.
  • Always arrive on time, ready to do the job.
  • Do the job better than anyone else, and for less.
  • Help the customer in any way possible

Why We're Different

What sets us apart is our recently designed and patented vibration data analysis process called ReVDAP.

ReVDAP is exceptionally powerful and provides an accurate and affordable alternative to analyzing data in-house. ReVDAP is offered exclusively by Vibration Analysts, Inc. and provides customers an exceptionally accurate, yet very affordable world-class vibration program. ReVDAP saves time and money by significantly reducing your PdM Program operating costs, while greatly improving equipment reliability. Compared to the traditional vibration programs, which have many limitations, ReVDAP provides ~99% accuracy in key program areas.

The main reason for our success is that ReVDAP is measurably superior to all other vibration programs in terms of:

  • Accuracy
  • Value and Affordability
  • Efficiency
  • Global Availability
  • Customer Benefits, including FREE 24/7 technical support, use of route data collection equipment and access to the vibration database software.


Ray W. Rhoe, P.E.


Ray W. Rhoe, P.E., is the President of Vibration Analysts, Inc. and is ISO-certified by the Vibration Institute as a Category IV vibration analyst.

After graduating from The Citadel in 1978, Ray began working in the “Noise Review Group” at a shipyard; building and overhauling SSN-688 class nuclear attack submarines. He later took a position with a nuclear power generation company as their vibration analyst/rotating component specialist.

Ray’s exceptional vibration test experience includes one of the largest operating deflection shape (ODS) tests ever performed in the power industry. This ODS test was performed on a 1250 megawatt Turbine Generator at a nuclear power plant and included two floors of the main turbine building.

Ray’s experience also includes on-site balancing, providing ISO certification training, as well as advanced component troubleshooting and testing.

In 2000, Ray formed the PMT Group in Oglesby, Illinois. In 2006, the team began working on ReVDAP.  After completing it and recognizing its many unique benefits, Ray patented the process, incorporated the business and changed our name to Vibration Analysts, Inc.

It’s who we are and it’s what we do.

Ray has attended a number of professional vibration training courses, including:

  • Practical Solutions to Machinery Vibrations – Update International
  • Category II Vibration Certification – Vibration Institute
  • Category III Vibration Certification – Vibration Institute
  • Category IV Vibration Certification – Vibration Institute
  • Operating Deflection Shapes (ODS) and Modal Analysis – CSI Inc.
  • Basic Machinery Diagnostics – Bently / Nevada
  • Advanced Machinery Diagnostics – Bently / Nevada
  • Balancing and Rotor Dynamics – Vibration Institute
  • Finite Element Analysis – RODYN

In addition to attending training, Ray also provides the following training courses:

  • Data Collector Training (Basic and Advanced)
  • Balancing Training
  • Category I Vibration Certification Training
  • Category II Vibration Certification Training
  • Category III Vibration Certification Training

Although managing VAI and resolving machinery vibration problems are Ray’s main “hobbies,” he also enjoys traveling the southwest, hiking, camping, backpacking, rafting and technical Jeep trails.
