How do you determine severity of vibration defects?

February 28, 2013

Severity determination is one of the most difficult tasks a vibration analyst faces. Several methods can be used to help identify the severity of defects identified in vibration data. One method is to consider the amplitude of the defect. This usually works well,  but does not always correctly identify the severity of the problem. Another […]

Alignment of Right Angle Drives or 90 Degree Gearboxes | Do you have the Right Angle?

February 26, 2013

Right angle drives,  or 90 degree gearboxes are very common in industry. These are speed reducer/increaser machines with an output shaft exiting at a 90 degree angle with respect to the input shaft. In some cases the 90 degree turn stays on the horizontal plane. This is great because the alignment can be treated as a […]

The Role of Vibration Analysis and Precision Alignment in the Design of an Award-Winning Reliability Program. What we learned from the Eastern Processing Facility at IMC-2012

February 21, 2013

The Reliability Support Team at the Eastern Processing Facility located at Cape Canaveral Air Force Station,  FL,  won Uptime Magazine’s Best Design for Reliability Program award. During the design phase of their program, the team was challenged with the implementation of Reliability-Centered Maintenance (RCM) principles and Precision and Predictive techniques from construction through commissioning. These have […]

Learn to Love Vibration with our Glossary of Useful Vibration Analysis Terms

February 14, 2013

Average – In vibration analysis,  an average usually refers to the process whereby the vibration software will,  after converting waveforms into spectrums via FFT, add the resultant spectrums together and then divide by the number of spectrums added together. The result is an “averaged spectrum”. Band – A band is simply a range of frequencies […]
