ACCEPTANCE TESTING

New Plant/Facility?  Putting new equipment into service?  Need to qualify new or refurbished equipment from suppliers?

VAI has highly qualified ISO Certified Category IV Analysts who can perform accurate and comprehensive acceptance tests to meet your requirements. We do more than just collect one data set and call it good.  We will support and witness all acceptance testing and perform according to specified operating conditions.  We support Acceptance Testing that includes coast up / coast down, natural frequency, resonant and “bump” testing, multiple data sets at specified operating conditions, and speed and operating condition variation.  We will also include a customized and detailed report documenting all data taken, along with results, recommendations and conclusions.

ADVANCED TESTING AND TROUBLESHOOTING

  • ODS (OPERATING DEFLECTION SHAPE) TESTING
  • MODAL ANALYSIS TESTING
  • MULTI-CHANNEL RECORDING AND ANALYSIS

 

ODS & Modal Analysis tests are quite similar.  ODS tests involves collecting data while the machine is in operation. This lets the machine generate the vibration data needed to determine how a machine is moving (the test results provide a 3-d animation of the machine’s movement).  Since both ODS and Modal Analysis Testing are very labor intensive, all other testing should be performed first.

ODS (OPERATING DEFLECTION SHAPE) TESTING

Modal Analysis Testing is different in that the Analyst uses ‘modal hammers’ to excite the vibration necessary which generates 3-d animations showing the machines expected movement. To date, VAI has determined that ODS testing is the preferred method simply because it provides the energy to create the data (much easier than wielding modal hammers).

Unless a machine vibration is excessively high (potential of failure during the test period) the ODS test may be the preferred test. Contact VAI for more information.

MULTI-CHANNEL RECORDING AND ANALYSIS

We can also perform a variety of different tests as needed depending on the situation. For more information, contact VAI at 815-742-1793 and tell us about your needs.
